nu halen nuværende NMOS er i lineære regionen, andre i aktive region, hvordan du justerer kredsløbet, så det kan fungere i aktive region?
forbløffende

 
Du bedes lægge dit kredsløb ....hvad du har beskrevet ved hjælp af tegn er ikke så klar ....

 
Du kan øge input transistor W / L at falde Vgs, så drain spænding af halen aktuelle kilde transistor stige.

. udgangen

 
det er vanskeligt at læse netlist, jeg går ud fra, at vi taler om den nuværende synkehastigheden for differenstryk par.Følgende forklaring er baseret på min antagelse:

Din NMOS dræn er i lineære regionen.
Tou vil behovet for at øge VDS på tværs af det, som kun kan incresed ved incresing gaten spænding på input af forskellen par.
Hvis du ikke kan gøre dette, thensee hvis du kan redues de vdsat for den aktuelle synke.
Hvis det ikke er muligt, ændre arkitektur.

 
fordi din vin> femte 2 * vdsat, din vthn = 450mv og vin = 787.48mv, så du skal redue de vdsat af den nuværende synker og input MOS
