Zdaj rep trenutno NMOS je v linearni regiji, drugi aktivno regiji, kako prilagoditi vezje, tako da lahko delujejo v aktivni regiji?
čudovit

 
prosim objavite svoje vezje ....kaj ste ga opisali z znaki, da ni jasno ....

 
lahko poveča vložek tranzistor W / L za zmanjšanje Vgs, da odteče napetosti rep trenutnega vira Tranzistor povečanje.

je težko brati netlist, jaz sem ob predpostavki, da govorimo o trenutni potapljanja za razliko par.Naslednjo razlago temelji na predpostavki, moj:

Vaš NMOS potapljanja v linearni regiji.
Tou bi bilo treba povečati Vds preko njega, ki se lahko samo incresed z incresing vrata napetosti na vnos razlike par.
Če ne morete storiti, da thensee če lahko redues vdsat za tekoče pomivalno korito.
Če to ni mogoče, spremenite arhitekture.

 
ker vaš vin> vth 2 * vdsat, vaš vthn = 450mv in vin = 787.48mv, zato morate redue vdsat sedanje potonejo ter šega input
