By Kelvin Yuk for the completion of EEC218A Originally published Dec 6, 2001 Abstract For the project, I propose to do the design and layout of a 4-bit serial adder. The serial adder is composed of two shift registers, one used as an accumulator for
A high-voltage (HV) SOI CMOS VLSI chip has been demonstrated to transport droplets on programmable paths across its coated surface. This HV exciter for a fluidic lab-on-a-chip system creates dielectrophoretic forces that move and help inject droplets
This is a brief tutorial on the use of ADS Momentum.
Investigation of power generation microdevices that utilize micromachining or MEMS for use in portable and self-powered systems. Autonomous and portable devices demand the need for small, lightweight energy supplies that can replace the use of conven
By Kelvin Yuk and Jackie Xue Originally published Mar 12, 2003 Introduction In our project, we explore two different circuit design optimization techniques. We first implement the steepest descent algorithm to exemplify some of the basic concepts in
