Noise performance of active RC-filters
Abstract
A general method is presented for conducting a noise analysis of second-order filter circuits containing a single amplifier. Attention is given to amplifier noise, the noise of the passive network, and the spectral density of the output noise power. Questions concerning an evaluation of noise in the case of circuits with differential amplifiers are considered. The classification of circuits is also discussed, taking into account the classification method, the noise transfer function, and the spectral power distribution of output noise.
