Abstract. This article presents a current-mode KHN multifunction biquadratic filter performing simultaneous 3 standard functions: low-pass, high-pass and band-pass functions, based on current follower transconductance amplifiers (CFTAs). The features of the circuit are that: the pole frequency and quality factor can be electronically tuned via the input bias currents. The circuit topology is very simple, consisting of merely 2 CFTAs and 2 grounded capacitors. Without any external resistor and… CONTINUE READING
