[SOLVED] using special functions of calculator in cadence

[dhaval4987]

Hello,

Can anyone tell me how to use the function phaseMargin in the cadence Analog environment calculator?

When i try to compute the Phase margin manually and compare it with cadence calculator, it doesnt match. the calculator number seems completely realistic. Can anyone tell me how to use it?

Got it. First evaluate, or simply write equation for gain (not dB) i.e., Vout/Vin, and then use PhaseMargin function on the value/equation in buffer. Dont forget to ADD 180 to the answer received.
