How to get -10volts DC from 10 volts peak to peak sine wave??How to Design the circuit??

 

Peak-to-peak means positive peak to negative peak. Many oscillator circuits exist - we need the desired frequency.

 

1. You can design a negative peak detector, or
2. Rectify the signal, average it and then invert and amplify it to -10V.

 

Use a votage doubler, followed by a regulator. Why are you doing this? A power supply? A detectror?

 

How to get -10volts DC from 10 volts peak to peak sine wave??How to Design the circuit??

This is a very general question.
Where you get the 10V peak to peak?
Why do you need -10V DC?
How many amps?
