Switched currents-a new technique for analog sampled-data signal processing

Abstract

A technique called 'switched currents,' for analog sampled-data signal processing in the current domain, is introduced. A family of modules that are capable of various computational and memory functions is described. The modules are well suited to system building as demonstrated by the simulation of a sixth-order Chebyshev low-pass filter. Circuit techniques that enhance analog performance are offered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
