Patent DE-3122504-A1 (DE)
Title: Current pulse generator
Inventor: NIELSEN NILS
IPC: H03K17/041
Filed: 1981-06-05
Abstract: A current pulse generator for generating square-wave current pulses via an operating load is described. The current pulse generator exhibits a current source supplying a constant current. A change-over device allows the constant current to flow alternately via the working load or a compensating load in accordance with the desired pulse characteristic. This results not only in square-wave pulses with a high edge steepness, but the current source is also constantly loaded in the case of pulses having widths within the micro-second range and below so that no transient processes occur. In a development, a voltage buffer circuit is provided which largely keeps the voltage level constant at the output of the current source, so that the current source is decoupled from the load changes due to the switch-over characteristic.
