Summary:
This paper introduces a mixed-mode biquadratic circuit employing Operational Transconductance Amplifiers(OTAs) and grounded capacitors. The circuit can perform mixed-mode operations by selecting the input and output terminals. And the circuit enables to realize low-pass, band-pass, high-pass, band-stop and all-pass transfer functions suitably choosing the input terminals. Additionally, the circuit parameters ω
0 and Q can be tuned orthogonally through adjusting the transconductance gains of the OTAs. An example is given together with simulated results by PSPICE.
