As this is clocked comparator, the best seems to use vccs sensing differential output and integrating it into capacitor connected to negative input (while positive input is on dc potential). Integrating capacitor should have initial conditions set to dc level on positive input and PSS should be...
Start with user guide. Virtuoso is delivered with high quality and comprehensive documentation. In case of issue, please show us your issue and what you want to achieve, too.
Linearity is quite a topic itself, while your statement is tricky to judge without investigation of your results.
What do you mean by true and pseudo class-AB stage? Is pseudo one, the class A bias structure with AC coupling for signal?
In general, input differential pair has non-linear...
Historically they are depletion mode MOSFETs. Currently in CMOS technologies, low threshold device can be obtained by low doping (or not using extra doping) and/or by using various gate materials with different electron work functions. Classic short channel effects are also used to lower the...
So 2nd point.
1. Create an assertion in ADE for the net you want: choose expression and define proper cross function (details you can find in SpectreMDL Reference manual → spectre_installation_dir/doc/mdlref/).
2. In transient analysis options: as actimes provide (@(assertion_name)) and in...
What you need?
1. Transfer result from one test and use it in another test?
2. In one test, find your event and run ac?
If 1 is valid then use calcVal function.
If 2 is valid, use spectre check to get event and call ac (proper document how to perform event triggered simulation is on CDNS...
It is a magic of negative feedback lowering impedance seen into feedback system.
Physically, you have difference in signal amplitude seen at the Capacitor both ends, but Capacitor capacitance is unchanged.
If your squarish block is an opamp, then two things (basically one):
1. Circuit is not working in negative feedback configuration
1a. if input pins name are correct, you are trying to make positive feedback loop
1b. with only capacitor in feedback, you have not established feedback loop in dc...
I can't imagine negative frequency in transient… Anyway, everything is possible to achieve in simple way, as long as you will not messing things.
Back to you question. You have syntax error. Proper example:
if(Output>500k then 1 else 2 )
Remember to avoid space betwen if and parenthesis. Also...
