Abstract

This paper proposes the complete electrical design of a new multiply-by-two amplifier to be readily used in highspeed medium/low resolution pipeline ADC stages. It is based in a switched-capacitor open-loop structure but with the novelty of having the gain accuracy improved by using an active amplifier with local feedback. Simulation results demonstrate that, with a very low-power dissipation and without employing any digital self-calibration or gain-control techniques, the circuit exhibits, over PVT corner and device mismatches, a dynamic performance and a gain-accuracy compatible with 6-bit level.
