I selected approx specs as---- Av=60 db,
CL=10pF, UGB=600kHz
UGB=gm1/2*pi*CL
which gives gm1= 37.699uA/V
seleceted branch current ID1=100nA
Which gives Gm/ID=37.699/100 K = 376.99.
Qslazio : I'm using TSMC 0.35 tech level 53
Else i don't think any other mistake i did in graph ploting of Gm/ID Vs ID/W.
Sutapanaki: what u r saying is correct. But does this mean that these specs cannot acheived with selected model file.
What i have in many papers that gm/Id lies in bet 0 to 28.
If during designing, people get gm/iD lets say arround 50, waht the do with this.........Need ur suggestion.
