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. WebJun 26, 2015 · Speedup capacitor. Note that some BJTs are designed to have a low saturation delay, expressly for their use as a switch. Specific impurities are diffused into the base region to increase the carrier recombination rate, thus reducing storage time.
