Abstract

This paper presents the 2-bit parallel algorithmic ADC using current mode for parallel method algorithm. It is operated by parallel conversion, 2-bit at each moment, and increase bit numbers by serial connection. The circuit operates in current mode. The comparison ratio can be controlled while working under mode operation. The circuit design used 0.8 ${\mu}{\textrm}{m}$ CMOS technology which capable to convert 2-bit in 50 ns, power consumed 0.786 nW, with input current 0-50 mA from 3V single supply. From simulation testing, the conversion rate is much faster than other method.
