TLDR
In this paper, a multiply-by-n switched capacitor amplifier, for n greater than 2, whose gain is insensitive to capacitance mismatch is presented, and the simulation results show that the variation in gain due to capacitor mismatch is much lesser than conventional architectures.Abstract:
Precision multiply-by-2 amplifiers have been researched intensively due to their use in pipelined analog-to-digital converters. For integer gains greater than 2, not much work has been reported. This work presents a multiply-by-n switched capacitor amplifier, for n greater than 2, whose gain is insensitive to capacitor mismatch. Simulation results show that the variation in gain due to capacitance mismatch is much lesser than conventional architectures.read more
