Abstract
The absolute value circuit of the invention comprises differential voltage to current converter means for converting an input voltage of alternating polarity into a pair of currents whose difference represents the input voltage, first and second inverter means for separately inverting each of the two currents, means for connecting the output of each inverter to the input of the other, the inverters being of the type which will only invert current of a predetermined polarity, and current summer and clamp means which are supplied with the outputs of the inverters for generating a unipolar output current signal whose magnitude represents the difference of absolute values of the pair of currents.
