Abstract
A high-speed continuous-time FIR (finite impulse response) filter comprises a plurality of processing cells configured in a cascade topology. Each processing cell receives a first signal and a second signal from a preceding circuit and a succeeding circuit, respectively, and outputs a third signal and a fourth signal to the succeeding circuit and the preceding circuit, respectively. Each processing cell further comprises a delay cell and a summing cell. Each of the delay cell and the summing cell performs a high speed signal processing using a combination of a feedback loop and a feedforward path.
