Abstract :
A systematic approach for ladder based switched-current (SI) filter design is described. Low sensitivity and low parameter spread SI circuits realised by both existing and novel structures can be derived from the proposed approach. The method can be applied to all the filter types and is well suited for computer aided implementation. Techniques to improve dynamic range and reduce circuit parameter spread are also presented. A 10th-order bandpass filter is used to demonstrate the utility of the approach
