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...

United Nations Environmental Concil SADD, Strategic Architectural Design Development - Chair of Materialisation

The building is the UN Environmental Council, the department of sustainability. Therefore the building should be sustainable itself. The building should have a clear position within the urban context of Manhattan. UNEC should also be open to the public with the measurement of the security, and also bring the nature to the new UNEC building. To...

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...

Multi-sensory Design in Detergent Powder Product Development

We experience the world through all our senses. People’s evaluation on the product is the same. It is very hard to measure how powerful the detergent product is or how clean the clothes really become. We make all the judgment through the information we receive from our senses. ‘Simplest way, best result’ as the core claim of ‘Dirt is good’...
