WebThe point of the 741's (and others) offset null pins is to let you eliminate the DC bias caused by input offset. In production test, you ground the input to the op-amp circuit and monitor its output with a volt meter. You then trim the offset-null potentiometer until the circuit output is 0 V. The offset null is not intended to "add a voltage ... WebBased on this, the main idea behind the proposed offset cancellation technique is to use body-voltage trimming in order to change the threshold voltage of the one of the input PMOS transistors (M 1/M 2) in such a way that the differential current (i diff), generated due to the mismatch effect, will be cancelled. tsi seed research

Webbipolar op amps, offset and drift are closely correlated where for each one millivolt of offset voltage at 25°C, one can expect to get about 3.3 µV/C of offset drift; Vos_drift = Vos(T) / (T + 273°C). This means that trimming the input offset voltage to zero assures that drift is also close to zero. However, when it
