These days, high-speed and communication portable systems employ voltage regulators that demandfaster response time. It is necessary to generate steps in line voltage and load current that are fast withrespect to the regulator’s control loop response time. Lab equipment and many apparatus that use opamps,passives, and large driver chains are limiting the rise and fall times of the stimulus s
