Abstract

A programmable load transient circuit includes a switchable power device for coupling a DUT output to its non-control node in series with a current sense device. A feedback loop is between the current sense device and the power device's control node that includes an integrator including an amplifier coupled to receive a signal that is a function of an average load current (I) supplied by the DUT from the current sense device and to receive a reference voltage (Vref). The integrator provides an output drive voltage that is coupled to an input of a level shifter which receives a pulse signal or DC level at another of its inputs. The level shifter provides an output waveform or DC voltage to the power device's control node that is a function of I.
