ABSTRACT:
In accordance with the present invention, two unsymmetrical differential amplifier stages are fed from a common signal source that supplies an AC voltage signal, but to which the two differential amplifier stages are connected with respect to the unsymmetry in opposite senses. The outputs of the two differential amplifier stages, however, are connected with respect to the unsymmetry in like sense and to an output circuit that provides the load resistances and whose output supplies the rectified a.c. voltage signal that also has an approximately quadratic characteristic.
