摘要：

This paper presents design techniques of switched-capacitor bandpass filters of the lossless-discrete-integrator (LDI) type which exhibit, simultaneously, good amplitude selectivity as well as good approximation to a constant group delay in the passband in an optimum manner. All the available degrees of freedom are exploited to shape both the amplitude and delay responses, in contrast to the available methods of delay equalization which yield suboptimal designs.
