Web1.2 Ideal Op Amp Model. The Thevenin amplifier model shown in Figure 1-1 is redrawn in Figure 1-2 showing standard op amp notation. An op amp is a differential to single-ended amplifier. It amplifies the voltage difference, V. d = V. p - V. n, on the input port and produces a voltage, V. o, on the output port that is referenced to ground. www ... Webamplifiers. One amplifier is a low-speed op amp with a small input offset voltage (µV). The second amplifier is a high-speed op amp with a large input offset voltage (mV). The same nulling-offset approach is taken for both op amps. 3.1 Effect of the Potentiometer on Vos The null circuit shown in Figure 4 was set up using a potentiometer.
