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.
