    I have this error on cadence , any help ?

    Thanks alot . I have another question .... I am working on TDC and I want input signal which is (LOW) and after few seconds becomes (HIGH) then still (HIgh), How can I get this on cadence ?

    using of gm rules in design mosfet circuit ?

    which gm rule can I use in design of simple mosfet amplifier circuit ? after designing such circuit and thus obtaining values of Id , W/l and Vod , should three rules of gm be equal or not ? gm rules I mean: gm=Un*Cox*W/l*Vod gm=2Id/Vod gm=sqrt(2Id*Un*Cox*W/l)

    Difference between hand analysis and simulator results ?

    Hi , I tried to design common source amplifier by hand analysis and obtained certain values of circuit parameter , then put these parameters into cadence simulator , after simulation I noticed that there is a big difference between the results obtained from hand analysis and others obtained from...

    Mosfet amplifier analysis ?

    Hello everybody ,why do we perform DC and AC analysis in mosfet amplifier ,is the voltage gain equal to the ac output voltage over the ac input voltage or the resultant of DC and AC voltages, and finally is Id the DC drain current or ac drain current such in this equation Id=.5 Kn*(Vov)^2 ?
