Abstract :
Switched capacitor biquads based on a loop consisting of two integrators generally require two operational amplifiers. A bandpass biquad is proposed which is derived by following a different philosophy based on successive voltage inversions. This allows the use of a single operational amplifier and the realisation of a bilinear transformed continuous-time transfer function.
