hi,
The plot you posted has the Time Scale obscured, cannot see it, so I have assumed a 500KHz 1Vppk Sine wave input.
As you can see there is some instability in the amp, I have also attached the FFT
EDIT:
Using a 100KHz sine wave input, gives image #3, which matches your 'doc' file plot
That is the one I am looking for. Thank you so much. Sorry, I did not reply yesterday.
I had lesson and checked with my friends too. I have one few initial mistakes in my first circuit.
I need one more help. Could you teach me how to set up for “transient response of voltage follower?
Kindly see the attaché doc file for reference.
I should find 1% settling time, (t)settle for a volt step <500ns
Thank you
hi,
With such a high open loop gain, the amplifier is switching from +/-Vout saturation, as it will.!
Its acting as a comparator because of the small imbalances in the circuit.
Exactly which parameter of the open loop amplifier are you trying measure when you apply the DC analysis, with one input connected to a fixed 0.63v.?????

The objective of the project is to design and simulate an operational amplifier which can
be used for high speed switched capacitor filters, in which the load is purely capacitive.
hi,
interesting OpAmp stuff ^ ^
i was wondering how u determine M7 W/L? was that a resister replacement? or current mirror?
pls enlighten me thanks.
sorry i'm abit new here
