Abstract
In this paper, we present A/D converter for signal processing of infrared sensor and CMOS image sensor. The A/D converter implemented in a 0.25um CMOS process provides a resolution of 10bits at a sampling rate of 50MS/s while dissipating 67mW from 2.5V supply voltage. This A/D converter is based on a pipelined architecture in which the number of bits converted per stage and the stage number are optimized to simultaneously achieve the desired linearity and reduce power consumption as well. Simulation results show that the A/D converter using 1.5bit per stage MDAC with switched capacitors and dynamic comparators efficiently reduces the power consumption.
