Question

What is A, B, C and D to design a voltage doubler in the given circuit?

(a) A=B=Resistors, C=D=Diodes

(b) A=D=Capacitors, B=C=Diodes

(c) A=Capacitor, B=D=Diodes, C=Resistor

(d) A=C=Diodes, B=D=Capacitors

I have been asked this question in homework.

I would like to ask this question from Clamper Circuit topic in section Diode Circuit of Analog Circuits

Answer 1

Correct option is (b) A=D=Capacitors, B=C=Diodes

The explanation: During the negative cycle, D1 conducts and C1 charges up to peak input. When the input is positive, then D2 conducts and C2 charges up to 2Vm. This creates a voltage doubler.
