In Reply to: RE: Sorry - can't quite see how to plot the Drain current ... posted by 13th Duke of Wymbourne on August 19, 2024 at 19:52:36:
As you can see from the circuit again:
... the circuit voltage at the Drains is 12.199v - so with an output sine wave of 200mV pp we are nowhere near clipping territory!
And yes, the input source is 500mVpp so there is attenuation in the complete circuit - not gain.
The actual gain stage has a gain of about 4x - IOW, the 50mV pp in (coming from the R3/R15 attenuator) becomes 200mV after going through the jfets.
