Operational Transconductance Amplifier Capacitor Networks for Higher Order Filters and Oscillators

Abstract

A generalized synthesis procedure of higher order OTA-C networks is presented. The general circuit configuration proposed can realize LP, HP and AP characteristics after inserting capacitors at the appropriate points. From the admittance matrix derived, the transfer functions are also obtained in terms of the capacitances of the network and transconductances of OTAs.
