Switched-capacitor multiply-by-two amplifier for high-resolution pipelined A/D converter
A new switched-capacitor multiply-by-two amplifier with an accurate gain of two is presented. The proposed architecture requires only one opamp in four phases to generate two effective outputs. It significantly suppresses the gain error due to capacitor-mismatch and also provides a better power efficiency. Monte-Carlo simulation results are presented to confirm the feasibility of this new technique, demonstrating its suitability for high-resolution pipelined A/D converter.
