Abstract

This paper proposes a novel finite-gain compensation technique that can be applied to low-voltage high-speed reset- and switched-opamp circuits. The proposed technique utilizes an Auxiliary Differential-Difference Amplifier (A-DDA) that senses and corrects the finite-gain error from the virtual ground of the main opamp (with the effective gain in the order of β∂ ), thus allowing the use of high-speed single-stage low-gain opamps (instead of usual lowspeed two-stage amplifier with large power consumption) to achieve high-speed operation. Simulations of a reset-opamp 10bit 100 MHz pipelined ADC in 1.2-V supply voltage are presented using 0.18μ CMOS, with the Signal-to-Noise-andDistortion Ratio (SNDR) improved from 46.77 dB to 58.51 dB and thus verifying the effectiveness of the proposed circuit. © 2006 IEEE.
