Original Abstract
The voltage-mode universal filter employing the active building block, namely voltage differencing differential difference amplifier (VDDDA) is proposed in this paper. The proposed filter has five input voltages and single output voltage. All input voltage nodes exhibit high impedance and the output voltage node is low impedance which is completely cascaded without the use of any external voltage buffer. The proposed filter realizes lowpass (LP), bandpass (BP), highpass (HP), bandstop (BS) and allpass (AP) filtering responses, without changing the circuit topology. The filter response can be selected by appropriately applying input voltage without any matching condition. The control of natural frequency and quality factor can be done electronically and independently. The proposed filter consists of three VDDDAs, two grounded capacitors and single grounded resistor. The performances of the proposed circuit are verified through PSpice simulation and experimental results. The results agree well with theoretical anticipations.
