Abstract
This work explains a voltage-mode universal filter with multiple input and single output terminals (MISO) using a single voltage differencing transconductance amplifier (VDTA), two capacitors, and one resistor. The proposed circuit offers simultaneous realization of all the five standard filtering functions; lowpass, highpass, bandpass, bandstop and allpass, without modifying the circuit configuration. Besides, the filter configuration provides an electronic adjustment of the natural angular frequency ±o and the quality factor (Q), and also exhibits low active and passive sensitivities. The proposed circuit performance diagnoses with PSPICE program, and confirm the theoretical predictions.
