how to generate pulse source with phase shift

Hi i am trying to simulate a laser driver circuit in ADS, how can i set pulse voltage sources to differential inputs with 180 degree phase shift?

Why not use a single floating voltage source?

But will that be differential signaling?

Hi,

An inverter?

Sure. You didn't specify intended common mode impedance.

I want to use MOSFETs to steer current to driver a laser source that's why i need pulse source to generate trigger signals. where i am confused is do i need two separate input signals or just single floating voltage source will work?
