摘要：

An approximate measure for the noise performance of integrator-based SC-filters of general order n is developed. The measure is dependent only on SC-design parameters like capacitor ratios and capacitance levels, but not on technology-dependent parameters describing the switches and amplifiers. A simple and explicit closed-form expression for this approximate noise measure is derived and compared with more complex-and accurate-measures. The comparison demonstrates extraordinary accuracy for our approximate noise computation. An important application for our noise measure is in the optimization of integrator-based SC-filters; it is used in the computer-aided design of sensitivity- and noise-optimized SC filters as described in the companion paper [1].
