WebOct 22, 2024 · Normally, op amps come with offset, so that voltage must be applied to one terminal in order for the voltages to be equal and, thus, for there to be 0 output. This is why op amps have offset null terminals. To … WebThe offset voltage of the main amplifier is measured and stored on capacitor CM2, while the stored voltage on capacitor CM1 adjusts for the offset of the nulling amplifier. The overall …
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.
