Search this article

Description

In this paper, new parasitic-insensitive first and necond order switched capacitor (SC) allpass filters having extemely low amplitude sensitivity are proposed. The proposed first order SC filter has zero amplitude sensitivity, and the proposed second order SC filter has a total absolute amplitude sensitivity below two. The proposed second order SC filter has one less operational amplifier than the SC filter given by Kato and Takebe. The parasitic-insensitive second order bandpass and band-elimination filters which can be realized by using the proposed second order allpass filter are described. Experimental results are given to illustrate the good performances of proposed SC filters.
