The bandwidths of these circuits are independent of their gains. The required capacitors are smaller than those described in previous work. Two new configurations of universal biquad filters based on these circuits are presented. A second-order bandpass filter, constructed using universal biquad filters, and a third-order Chebyshev lowpass filter, with 1 dB passband ripple, are breadboarded. Measured results are presented.Bandpass filters; Bandwidth; Capacitance; Capacitors; Computer simulation; Harmonic distortion; Integrating circuits; Low pass filters; Operational amplifiers; Transfer functions; Chebyshev lowpass filter; MOSFET-C integrator; Operational transresistance amplifiers; Parasitic capacitance effect; Software Package SPICE; Total harmonic distortion; Universal biquad filters; MOSFET devicesjournal article10.1049/ip-cds:200105232-s2.0-0035493945WOS:000172102700003
