Abstract
A differential amplifier, preferably comprised of N-channel MOS devices and having a high ratio of differential gain to common mode gain, has an input stage which receives first and second potentials and amplifies the difference therebetween. Additional amplifying stages each include a depletion input load device having a gate which is coupled to the second potential for balancing the switching points of each additional stage over the common mode range.
