Abstract :
The noise analysis of continuous-time active-RC filters is presented, based on a general model of an integrator-based active-RC filter, which is analyzed using a matrix description. A compact and explicit procedure for evaluating the input/output referred noise spectrum of any filter of this class is derived. The algebraic approach is employed especially for efficient use in computer-aided design and optimization of active-RC filters. An application example of the proposed approach to noise optimization of a 3rd order Chebyshev filter is given.
