Abstract :
This paper describes a number of simple (first-, second-, or third-order) switched-capacitor circuits. These can be used as simple self-contained filters, or as filter sections in the cascade realization of a higher order transfer function. All these sections are free from parasitic effects, and all can be designed directly in the sampled-signal domain. Low-pass, high-pass, bandpass, and all-pass circuits are discussed, with and without finite nonzero transmission zeros.
