Abstract
Noise in Gm-C filters is discussed, Topology-independent bounds for th e signal-to-noise ratio (SNR) are derived, assuming the total power di ssipation or the total capacitance are specified, Expressions for cert ain products of noise with frequently used quantities are derived, and are shown to be invariant under certain actions, which are sometimes taken in order to improve the SNR, Finally, specification-dependent bo unds for SNR are derived.
