Abstract :
A technique is described for achieving low-voltage offset and thermal drift in a monolithic integrated differential amplifier. First order compensation is achieved, under severe restrictions, for a simple differential pair. An alternative balancing technique utilizes the linear combination of two equal and opposite drift characteristics to minimize drift from all sources. Drift values of /spl plusmn/0.12 /spl mu/V//spl deg/C over the temperature range 0 to 100/spl deg/C have been obtained.
