    Gain Saturation in Common Source Amplifier

    It Looks like your output impedance falls due to substrate-current-induced body effect. Can you check if you have current leackage into you bulk?

    Cadence Spectre - DC Analysis after Transient

    In spectre each voltage source typiccaly has parameter "DC voltage" this voltage will be used by DC simulation. Set this voltage to what it needs to be.

    Funny MonteCarlo Phase response when doing Middlebrook

    Hi, To me it looks like amp is falling over on corners. When you run corners do you see similar phase behaviour? Can you run monte carlo mismatch only?

    MIM capacitance parasitics

    Extractions can sometimes be missleading. 4p is way too large capacitance. You can check it by extracting and by old good hand calculations with the ruler and some number from the process.

    How can I simulate "Click and Pop noise" in Hspice

    Re: How can I simulate "Click and Pop noise" in Hs wkjo82 - It is difficult to say without seeing your architecture where would be best place to add offset. - But as a general rule you need to add it at the input of your first amp a series voltage source with one of the inputs and you should...

    How can I simulate "Click and Pop noise" in Hspice

    Re: How can I simulate "Click and Pop noise" in Hs You need to have offset in your amp so that you can see larger pop/click. Do you simulate with an offset?
