Abstract
Noise in Gm-C filters is discussed. Topologyindependent bounds for the signal-to-noise ratio (SNR) are derived, assuming the total power dissipation or the total capacitance are specified. Expressions for certain 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 bounds for SNR are derived. © 1998 IEEEKeywords
