High input impedance first-order allpass, highpass and lowpass filters with grounded capacitor using single DVCC

摘要

A voltage-mode high input impedance first-order allpass, highpass and lowpass filters using one differential voltage current conveyor (DVCC), one grounded capacitor and two resistors is presented. The allpass, highpass and lowpass signals can be obtained simultaneously from the circuit configuration. The simulation results confirm the theoretical analysis.
