Towards Real-Time Detection and Tracking of Spatio-Temporal Features: Rodent Whisker Tracking

The rodent whisker system is becoming a prominent experimental subject for the study of active sensing. As a result of improved video recording hardware/software and progressively better neurophysiological methods, there is now the prospect of precisely analyzing the intact vibrissal sensorimotor system. The vibrissae and snout analyzer (ViSA),...

Emitter Switching for Power BJT Based LED Drivers

In recent years, the LED lighting developed rapidly because of its superior efficiency, eco-friendliness, and longer lifetime compared to the fluorescent and its incandescent counterparts. As the core of LED systems, LED drivers need to be well designed in order to properly drive the LEDs with high efficiency, high reliability, long lifetime,...

Monolithic integration of light sensor readout system for multi-functional LED wafer-level packaging based on BICMOS process

LED-based lighting is becoming increasingly popular in recent year, but LED development especially for lighting application now seems unavoidable. The various benefits of LEDs and the continuous increase in their performance allied to the decrease of the manufacturing costs makes it quite attractive. It is widely believed that LEDs would be a...

A Fast and Accurate SystemC / SystemC-AMS Model for Super-Regenerative Radio

A new and precise mixed-signal model for a super-regenerative radio system based on the recent published language SystemC/SystemC-AMS is presented in this thesis. The simulation time of the model is dramatically reduced so that the PLL is able to be included into the model to simulate the frequency difference between the transmitter and receiver...

Pixel ADC Design for Hybrid CMOS Image Sensors

This thesis presents the design of a pixel level analog-to-digital converter (ADC) circuit for hybrid CMOS image sensors. There are several methods to increase the dynamic range of the sensor through the readout algorithm. The multiple sampling method can increase the dynamic range (DR) without a loss of signal-to-noise ratio (SNR). The idea is...
