Low-power leapfrog bandpass filter with transmission zeros using integrators and resistor-based addition circuits

This paper proposes an approach to realize a leapfrog filter with transmission zeros by using OTA-C integrators and resistor-based addition circuit instead of OTAs. This method has advantages of reduced number of active elements and spread of element values. A tenth-order bandpass filter is presented as a design example.
