WebCircuit Description. Circuit Graph. The circuit demonstrates the Vbe multiplier (the circuit formed by Q1, Rbe, and Rbc), a shunt voltage regulator that is often used to bias a push-pull output stage of a BJT amplifier. One interesting property of the Vbe multiplier is the convenience it offers when tracking the thermally induced variation in ... WebThe capacitor equation says i = C dv/dt. The sharp transition means dv/dt will be a very large value for a very short time. If the voltage transition is instantaneous the equation predicts a pulse of infinite current in zero time. The reason this simple circuit is troublesome is because no resistor is involved.
