Low voltage switched-current cell and its application

Abstract (Summary)

In recent years, a new analog sampling design called Switched-Current has generated interest for its potential to reduce manufacturing costs by allowing interface circuitry, such as Analog-to-Digital and Digital-to-Analog Converters, to be manufactured using a standard digital CMOS process. This thesis presents Class A First-Generation and Class AB First-Generation Switched-Current designs and also presents techniques for correcting switch-induced errors. The Class A and Class AB designs are simulated with a voltage supply of 0.9V using Linear Technologies LTSpice and a 0.18┬Ám transistor model. The Class AB design used less power than the Class A design and also had less Total Harmonic Distortion. However, the Class AB results were achieved at a lower sampling frequency compared to the Class A design. At lower supply voltages the Class AB design was able to handle higher sampling frequencies compared to the Class A.
