I know that it is possible to use MOSFET as regulated resistor if following conditions are met:
Is it possible to fine tune RDS of a MOSFET so that:
- VGS > Vthreshold
- VGS < VDS
- Vforward = 3.45V
- Iforward = 20mA
Is it possible to fine tune RDS of a MOSFET so that:
- At 9V from trimmer, RDS = 330Ω
- At 0V from trimmer, RDS = 1kΩ
- Or vice-versa
