Abstract :
A novel clock feedthrough reduction circuit which is helpful in the design of switched-current filters is proposed. This circuit uses the cancellation technique. A switched-current FIR (finite impulse response) filter adopting the proposed circuit is designed. Simulation of the prototype filter circuit reveals good results. It has a small chip area and higher operating frequency in comparison with the conventional methods
