Abstract

A low voltage rail to rail highly linear voltage to current conversion technique is presented. This is based on flipped voltage follower regulated cascode mirror. As an example application of this technique, a current mode successive approximation analog-to-digital converter (ADC) architecture is presented. Cadence simulation results of the 8-bit ADC are presented which show that the ADC works in range up to 202 KS/s with a single supply of 1.8 V and 3.21mW static power dissipation in 0.5μm CMOS technology.
