Re: [help] can mosfet work in linear(triode) region in vccs(with op amp)?
Thanks, dick_freebird & FvM
but I want to know what is limited voltage range("But a current source
that only works right over a limited voltage range")
and MOSFET Power dissipation P_dis = Vds*Ids, the need Vds is smaller working in linear range than saturation. so the power will be reduced, isn't it?
BTW, In my testing board, there will be a periodic Pk-pk 50mA 50Mhz ripple reducing vds into linear range, is it the only negative factor working in the linear range?
