Abstract

This full-wave voltage rectifier provides balanced outputs + Alpha absolute value of V and -Alpha Absolute value of V where Alpha approximates 1. For a negative signal -V, the signal being fed to the inverting input, diode D1 is forward biased while D2 is backward biased. The circuit acts, therefore, as an operational amplifier providing an output signal V1 = -2R'/(2R'+R)(-V) = 2R'/(2R'+R) absolute value of -V, if the load impedance R" is very high. For a positive signal +V, D1 is off and D2 is on. The circuit acts as a voltage divider to provide an output ..LAYOUT 4 signal V1=2R'/(2R'+R) absolute value of +V. Therefore the overall V1 output signal is V1=2R'/(2R'+R) absolute value of V=Alpha absolute value of V. Similarly, V2 = -Alpha absolute value of V. If R' is much higher than R, Alpha approx. equals 1. ..LAYOUT 1
