A New Transadmittance Type First-Order Allpass Filter Employing Single Third Generation Current Conveyor

摘要

A novel transadmittance (TA) mode first-order all-pass filter configuration is proposed. The proposed circuit uses a third generation current conveyor (CCIII), three resistors and a grounded capacitor. The output of the filter exhibits high output impedance so that the synthesized filter can be cascaded without additional buffers. The theoretical results are verified with PSPICE simulations using a CMOS realization of CCIII.
