WitrynaWe can build an op-amp circuit which measures change in voltage by measuring current through a capacitor, and outputs a voltage proportional to that current: The Virtual Ground Effect The right-hand side of the capacitor is held to a voltage of 0 volts, due to the “virtual ground” effect. WitrynaOne useful function of a buffer (voltage gain of 1) amplifier is to prevent interfering signals at stage 2 from propogating to stage 1 of a signal-processing chain. So, a buffer between a source and a long wire connection will serve to prevent antenna-like pickup on the wire from disturbing the source. terbatah batah
