Hi all,
I am studying cs_mosfet amplifier and i have simulate one simple amplifier with VDD=+12v Vs=1v ID=0.5mA gm=1mA/v Vd=6v. I am getting a signal that is amplified by gain -11.3 by calculation and also on simulation but when doing on hardware i am getting gain around -40 to -45
I am using Bs 170 mosfet.
I have tried various combination of capacitors but still gain comes around -40...can anybody suggest me where is the mistake?
