Subtract of two electrical signals

[Pavlanto]

Hi,
I am using Cadence virtuoso and i have used a track and hold circuit where i take the output differential. In the next stage i need this output to have it in a single mode,which means i want to have Voutall=Voutp-Voutn. What is the way to do it so?
Thanks

You use a differential input amplifier with a single-ended output.

you can also use Balun circuit block.

Try this circuit to subtract two voltages

the key point is the common mode voltage of these two input. Anyway you can get enough reference circuit from LT6375 data sheet. It would support +-270V common mode voltage.

Good luck.
