Abstract

A new first-order voltage-mode filter employing minimum active and passive components is proposed. The proposed configuration employs one differential voltage current conveyor, one grounded capacitor and one resistor. It maintains the following advantageous: (i) employment of only one current conveyor, (ii) employment of only one grounded capacitor, (iii) employment of only one resistor, (iv) simultaneous realization of voltage-mode first-order lowpass, highpass and allpass filter responses from the same configuration, (v) no need to impose component choice conditions and (vi) low active and passive sensitivity performances. HSPICE simulation results using TSMC 0.18 μm 1P6M CMOS process and ±0.9V supply voltages validate the theoretical predictions.
