Hi. Y'all

The attached file is one of relaxation oscillators I am using. This circuit specifically uses a TI’s TLC3702 comparator to generate a square wave output.

Can you perform a pss (periodic steady state) and phase noise analysis for this relaxation oscillator in Multisim? My first software, Cadence, has both simulations. However, I can’t generate the same specification with the comparator in Cadence. That's why I try to use the Multisim. I hope this is the best choice (well, if it can run the both simulations)

The pss simulation should be output (frequency) versus parameter (sweep). For example in the circuit, I would like to know the frequency change against the capacitance change in Cf while Cs and Rf are fixed.

Any idea would be a great help. Thank you
