Phase Sensitive Detection Based on FPAA

Abstract:

Application of FPAA (field programmable analog array) for the construction of phase-sensitive detector is described. The working principle of the phase sensitive detector is introduced. With software called Anadigmdesigner2, a signal selection circuit, a inverting circuit, a rectifier and a low pass filter circuit are achieved. The simulation of the phase-sensitive detector circuit designed is made. Phase rang from 75º to 115 º, phase errors detected are below ±0.392%.
