Very-low-drop diode simulator

Very-low-drop diode simulator
In certain applications it may be desirable, in order to limit unnecessary power losses, to have the use of a diode with a forward voltage lower than 0.7 V. The present circuit fulfils that desire. At a forward current of 1 A, the total drop across the two (active) components is only 0.04 V - an appreciable reduction compared with a standard diode.
