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 thel/ptransformation wherep =(1 -z⁻²)/ {τ}can be performed for such filters similarly to Bruton's1/stransformation for analog continuous networks. An analog sampled-data filter based on this principle has been designed and implemented using discrete components.
