Abstract

A by-inspection analysis method for multiphase switched-current (SI) circuits using signal-flow graph (SFG) techniques is presented. The derivation of the SFG is on the transistor level and is primarily useful for the hand analysis and design of small and medium-size SI circuits (e.g., SI filters, decimators, interpolators). Tables of commonly used SI circuits, in which the corresponding SFGs are given, make the derivation easy and fast. Not only the overall discrete-time transfer functions, but also the ones between individual switching phases, are obtainable
