Abstract
This paper presents a 6-digit Analog-to-Quaternary Converter (AQC) using a 0.35 mum CMOS process. The proposed CMOS AQC uses pipelined architecture with redundant signed digit (RSD) error correction algorithm. A CMOS quaternary adder is proposed to handle quaternary addition in the correction algorithm. The converter has simulated SNDR SFDR and THD of 65.17 dB, 73.89d B and -73.26 dB at 2.5V supply voltage and 50 MHz sampling rate.
