Arrangement for transient-current testing of a digital electronic CMOS circuit

摘要

For transient-current testing of an electronic circuit, a differentiating current measuring device is arranged for measuring an undershoot voltage for each of a series of current pulses controlled in the circuit. In particular, the device is executed in integrated circuit technology and simulates a differentiating current probe. Furthermore, it may have calibration for imparting an offset voltage to each undershoot voltage of the series. This calibrates an actual potential of the simulation and produces for a correct Device Under Test in each cycle a substantially uniform undershoot voltage.
