Optimization Techniques for Circuit Design
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
A High-Voltage SOI CMOS Exciter Chip for a Programmable Fluidic Processor System
A high-voltage (HV) integrated circuit has been demonstrated to transport fluidic droplet samples on programmable paths across the array of driving electrodes on its hydrophobically coated surface. This exciter chip is the engine for dielectrophoresi
A High-Voltage CMOS VLSI Programmable Fluidic Processor Chip
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
