Abstract :
The half-band filtering technique is an efficient approach especially for 2-fold sampling rate alterations. This paper proposes novel Switched-Capacitor (SC) architectures for sampled-data analog half-band impulse sampled interpolations whose system responses are also immune to the input sample-and-hold filtering effect distortion. Three alternative architectures are investigated with their corresponding comparative superiority from the viewpoints of required number of amplifiers and passive SC branches as well as clock phases. An effective multistage implementation of SC interpolation based on the newly proposed half-band interpolators is also described with further comparison among traditional designs
