Transadmittance Mode First Order LP/HP/AP Filter and its Application as an Oscillator

摘要

In this paper new transadmittance mode first order low pass, high pass and all pass filter topologies using operational floating current conveyor (OFCC) is proposed and its application as an oscillator is also put forward. This proposal offers all filter functions at high impedance. Only two OFCCs, two resistors and one grounded capacitor are employed for realization. Workability is verified through SPICE simulations and results conform to the theoretical predictions very well. The proposed circuit is prototyped and tested experimentally for its application as an oscillator.
