Analog FIR Filters by Switched-Capacitor Techniques
Date of Original Version
This paper addresses the implementation of general purose FIR filters by stray-insensitive SC techniques. First, a simple building block for an analog tapped delay line is introduced. The proposed cell comprises a single amplifier and is controlled by a multiphase clocking scheme. Then it is shown how this circuit can be developed into a generic FIR filter cell without the need for additional amplifiers. The feasibility of the new building blocks is demonstrated by example of a linear-phase low-pass filter design. © 1990 IEEE
