Analog multiplier is a key nonlinear computational block with which almost all useful nonlinearr functions can be synthesized. The multiplier used as a correlator is an essential part of a VLSI adaptive filter. It is also used in many other applications, includ-ing signal processing (modulators), measurements (wattmeters,flowmeters), rms-dc conversion, etc.
