Abstract :
Switched-current (SI) circuits are proposed for realizing decimation and interpolation filtering functions with both finite impulse response (FIR) and infinite impulse response (IIR). An efficient switching is discussed which improves the performance of the proposed SI multirate circuits affected by settling time errors of the memory cells
