Pulse generator circuit

摘要

A pulse generator for generating pulses having predetermined slopes is disclosed, comprising a capacitor that can be charged and discharged through predetermined current sources, a switching device for connecting and disconnecting the current sources and a step function signal source for controlling the switching device. The capacitance of the capacitor is in the range of the stray capacitance of the switching device. A fraction of the output signal of the step function signal source is superimposed in oppposite phase upon the output signal of the capacitor so as to compensate the voltage surge in the output signal of the capacitor resulting from the voltage divider formed by the stray capacitance of the switching device and the capacitor.
