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 tripler. The output voltage is approximately equal to 3.0 V
