General results for resistive noise in active RC and MOSFET-C filters

Abstract

Resistive noise in active RC and MOSFET-C filters is examined. The effects of impedance and frequency scaling are shown. The relationship between sensitivity and noise is considered. A bound for the product of resistive power dissipation and noise power spectral density is derived. Topology-independent and transfer function-independent bounds for the dynamic range, in filters with power dissipation constraint, are developed.
