minus the forward voltage drop of each external diode. The performance characteristics for the above converter are shown
below. Note that curves A and C show the circuit performance with economical 1N4148 diodes, while curves B and D are with
lower loss MBRA120E Schottky diodes.
A single device can be used to construct a positive voltage doubler. The output voltage is approximately equal to 2.0 V
