Switched-capacitor filters using FDNR-like super capacitances

Switched-capacitor networks have become very attractive for the MOS/LSI realization of analog sampled-data filters. The work presented in this paper shows that the
l/p
transformation where
p =(1 -z^{-2})/ {\tau}
can be performed for such filters similarly to Bruton's
1/s
transformation for analog continuous networks. An analog sampled-data filter based on this principle has been designed and implemented using discrete components.
