Abstract :
In cascade realization of active RC, switched-capacitor, and OTA filters, it is desirable to have lower Q values of the pole pairs. The author compares various Q-reducing methods in the design of filters having equal ripples in passband. Two examples are provided to quantitatively illustrate the relative merits of each method in time domain as well as frequency domain
