Recently deep learning has become one of the most powerful and popular machine learning techniques due to its record-breaking performances in a variety of recognition tasks including speech recognition and image classification. Deep learning also changed the paradigm of pattern recognition in that it allows us to automatically discover hierarchical features from data instead of relying on hand-crafted features. In this tutorial, I will provide an overview of deep learning discussing what have been the main difficulties of training deep neural networks and how these difficulties have been overcome by recent breakthroughs. I will also introduce several deep learning techniques such as restricted Boltzmann machine (RBM), deep belief network (DBN), deep neural network (DNN), and convolutional neural network (CNN) and talk about how they are applied to computer vision problems such as a large scale image classification.

Wearable healthcare sensor provides attractive opportunity for semiconductor sector. The target here is to mitigate the impact of chronic diseases by providing continuous yet adequate low noise monitoring and analysis of physiological signals. Wearable environment is challenging for circuit designers due to its unstable skin-electrode interface to begin with. Wet and dry electrodes have very different electrical characteristic that needs to be addressed. Also, in wearable environment, trade-off between available resource and performance among the components (analog front-end and digital back-end) is of crucial.
This short course will cover the design strategies of bio interface circuits for such wearable sensors. We will first explorer the difficulties, limitations and potential pitfalls in wearable interface and strategies to overcome such issues. After that, system level considerations for better key metrics such as energy efficiency will be introduced. Several state-of-the-art instrumentation amplifiers that emphasize on different parameters will also be discussed. We will then see how the signal analysis part impacts the analog interface circuit design; we will also cover how we can achieve patient-specific monitoring. The talk will conclude with interesting aspects and opportunities that lie ahead.

Continuous health monitoring in hospital and/or home conditions has been of interest to doctors and healthcare practitioners for a long time. Recording of physiological and psychological variables in real-life conditions could be especially useful in management of accurate and chronic disorders or health problems, e.g., for stoke, shock, high blood pressure, diabetes, neural disorder, chronic pain, or severe obesity etc.. Physiological signals have been used as important indicator of the vital signs of human kinds, and real time monitoring of various physiological signals can predicate and be preventive to many serious life attacks. Furthermore, real-life long-term monitoring of health could be good measurement of treatment effects at home care, in situations where the subjects live their daily life. In this tutorial, firstly we will introduce and cover different types of physiological signals such as electrocardiogram (ECG), blood oxygen saturation (SO2), neural spike, blood core temperature, and Glucose etc. Secondly, the typical and vibrant integrated wearable or patchable sensors to acquire and measure the physiological signals are introduced and presented.

CMOS Image Sensor and Its Noise

- Master of Electrical Engineering & Computer Science, KAIST (1998~1999)
- Ph.D of Electrical Engineering & Computer Science, KAIST (2000~2004)

In this lecture, as a first, I will review the recent CMOS image sensorâ€™s application and technology development trend. And then, as a next, I will introduce the understanding and the developing status on the Image Noise. Recently the application area of the CMOS Image Sensor become wide continuously and, mainly, it can be divided as Mobile Phone, High-end Camera (DSLR/DSC), Time-of-Flight, Automotive, Security, Medial, and Science & Space area. The market demand for the CIS technology increases even yet and nowadays, thanks to appearance of the Dual camera system in mobile phone, its demand expects to become twice simply. Automotive Sensor is also very impressive application market but needs higher reliability and frame rate than other applications. Security Sensor receives the attention with increasing needs on the social safety request. The main medical sensor is the capsule endoscope and X-ray sensor.
Even though many application areas there are, the main technology stem can be listed as two types. Fist one is the FSI (Frontside Illumination) and second one is the BSI (Backside Illumination). As well-known, the FSI technology is based on the traditional semiconductor processing technology and many important technologies have been developed, but due to the process limitation, now this is used for making the large pixel products and some special aim sensors.
The BSI technology shows so impressive performance but have so complicate process and high cost at the same time. Nevertheless, recently the BSI technology applied for the high-end camera and become general trend and this expand its application area to the large pixel products continuously.
These application conditions and process technology developments in CMOS Image Sensor is always running with the understanding of the Image Noise. This understanding of the Image Noise acts as one of the big motivation of technology development. To understand the Image noise, I will review the operation of the unit pixel at first and then design and layout related noise will be reviewed, too. List up the noise from the image and then also summarize and understand the physical basis of these noises, we can imagine the technical method to solve these noises. I check the direction of the technology development from the review of recent results to improve the image quality in the process and design area. This will give us the opportunity to develop more improved products.

Amplifiers form the core of many analog and mixed-signal circuits. However, the design of differential pair based OTAs is becoming increasingly difficult in finer geometries due to lower supply voltages. Inverter based designs have proven to have better transconductance efficiency, higher swing and better linearity but have degraded CMRR, worse PSRR and limited PVT tolerance. In this tutorial, we discuss traditional amplifiers and why inverter based amplifiers are better suited for lower supplies. We then describe the design procedure for inverter based OTA designs with an emphasis on improving their performance, including PVT tolerance, CMRR and PSRR. In particular, we introduce new biasing techniques for inverters to improve their PVT tolerance. We will finally validate our designs using measurement results from a number of fabricated designs.

Low-power, high-resolution analog-to-digital converters (ADCs) are highly required in many sensor applications. Such ADCs often result in poor energy-efficiency and high-power consumption, thus making them unsuitable for the use in battery-powered sensor systems. This tutorial covers the design of low-power high-resolution ADCs for smart sensor interfaces, which include both architectural- and circuit- level techniques to maintain their power-efficiency. It also describes practical design aspects from several design examples.
