Özet

In this work, a novel general circuit configuration for realizing differential-mode first-order all-pass and second-order all-pass/notch filters with high common-mode rejection ratio (CMRR) is presented. The proposed circuit is based on a differential voltage current conveyor (DVCC). The circuit uses only one resistor and three capacitors for realizing a first-order allpass filter and three resistors and three capacitors for realizing second-order allpass/notch filter. The non-ideality analysis of the configuration is given. SPICE simulation results are included to verify the theory.
