Abstract
A balanced amplifier includes first and second multi-input single-ended output differential amplifiers having matched characteristics and a feedback circuit. The feedback circuit connects differential input terminals and output terminals of the first and second multi-input single-ended output differential amplifiers so that all of the differential input terminals of the first and second multi-input single-ended output differential amplifiers are virtually shorted.
