Can I get a single output out of a long tail inverter?
« on: October 05, 2025, 03:57:44 pm »
A stupid question... a phase inverter gives us two output signals out of phase. Is it possible to get a single signal out of it instead of two?


I know it's possible to combine those two signals into a single one with a triode amplifier, is it possible to do it without another extra triode?


Thanks

not sure your end-game since 2 out of phase signal cancel each other...sorta.

Why do you want to do this?

Sure. Simply connect one of the signals and don't use the other one.

Sure. Simply connect one of the signals and don't use the other one.

The only downside to note is you might have half the signal-size you'd otherwise get if you just used a "triode gain stage."
