  • Abstract
    The technique of employing one operational amplifier merely to cancel, or partially cancel, the voltage offsets and drift effects of its twin on the same semiconductor wafer makes possible, at low cost, a d.c. computing amplifier with a drift performance an order of magnitude better than that of a single amplifier used by itself.
