WebNote that the Figure 1 circuit will continue to function if the RV1 offset-nulling network is removed, but its output may offset by an amount equal to the op-amp’s input offset voltage (typically 1mV in a 741) multiplied by the closed-loop voltage gain (A) of the circuit, e.g., if the circuit has a gain of x100, the output may be offset by 100mV with zero input applied. WebTranscribed image text: 5) One approach to "offset correction" involves the adjustment of the values of Rc1 and Rc2 so as to reduce the differential output voltage to zero when both input terminals are grounded. This offset- nulling process can be accomplished by utilizing a potentiometer in the collector circuit, as shown in the circuit below. incorporatewear oldbury https://lyonmeade.com
