IMPLEMENTATION OF NON-LINEAR ANALOG SIGNAL PROCESSING CIRCUITS

Abstract

The presence of several nonlinear analog circuits with reduced components count, low power supply, better accuracy and fast speed is an extremely challenging task. This project work describes implementation of CMOS based non-linear analog signals processing circuits like: multiplier, squaring circuit, Schmitt trigger, full-wave rectifier circuit, etc. These non-linear circuits have their important applications in wireless communication and image & pattern recognition. These fields have been well established for a long time now. However, in the wireless communication applications, the available bandwidths are being stretched too much and the search is on to make circuits and systems that tap the previously unused GHz range. Such a problem to make use of available bandwidth in communication system can be solved by the use of non-linear analog circuit. The squaring circuit and rectifier circuit have a very good frequency response and have advantage to be used in communication system. Bot...
