<p>The compensation circuit has an input voltage (Vin) fed to the positive terminal of an operational amplifier via two series resistances (R1,R2). There is a switch to earth (SW) between the two resistors. A reference voltage (Vref) is applied to the positive Operational Amplifier voltage terminal via a parallel resistor (R3). A positive voltage compensation bigger than the possible difference voltage is produced using this method.</p> |
