Thanks for reply, I‘ve tried,and I think the default parameters do not affect the performance. This is because the input impedance looking into source is 1/gm which is 2.2K,smaller than the input impedance of amplifier model, bandwidth may affect the time characterists,but may not affect the ac...
To verify the gain boosted, I design this easily to understand models which are as follows.
Fig.1 is the common gate amplify structure,
Input source is bottom voltage source V19 which has AC and DC signal shown below
Both two transistors are in saturation region and I add an inductor with...
I did not plot the detail Z which is a cascode NMOS structure using gain boosted structure just like the upper lanch. Z is an inductor seriesing the cascode structure.
Hi
I’m designing an opamp with gain-boosted structure,but I encountered an problem.
By some techniques,I made the CMFB ideal(using ideal Vcvs to sense output),so the Cmfb circuit will not affect the differential output impedance. By seriesing a large inductor, the bottom impedance of Z is...
