Sensitivity and high-frequency performance of new wave active filters

Wave active filters with reduced numbers of operational amplifiers are studied with regard to their sensitivity and the operation at high frequencies. An effective method of compensation for the effect of the finite gain/bandwidth product of the operational amplifiers is suggested and applied successfully. Finally, a `lossy¿ and a `lossless¿ WAF realising the same 6th-order bandpass function are compared with respect to their sensitivity and suitability for high-frequency operation.
