Abstract

Noise analysis of switched capacitor amplifier-based sensor interface circuit has been presented in this paper. It is shown that the main noise of the circuit has been generated by the amplifier. Even though specification of the switches effects the efficiency of the circuit, their influence on the output referred noise is trivial and can be ignored. The circuit has been simulated with ELDO in UMC 130nm technology. Approximate expressions for the output referred thermal noises are derived and the accuracy of the noise modeling is verified by the simulations.
