Abstract :
Several approaches have been introduced to implement narrowband filters in the context of switched-capacitor circuits. In this paper effects of random capacitance ratio errors on the frequency response of interpolated finite impulse response (IFIR) filters are considered. Emphasis is given to the aliasing effects due to mismatches among unit capacitances in the delay circuit of the IFIR filter
