Voltage Controlled Resistor
Voltage Controlled Resistor
(OP)
Anyone,
I need a voltage controlled resistor that can produce 0 to 1M ohms resistence with 0 to 15vdc or 0 to 28vdc input power. Any suggestions? I heard FET can be used but how can I produce 0 to 1M?

Simulate the circuit to act as thermostat, and for the sensor to read resitance of circuit(in replace of thermostat). The resitance of thermostat goes higher as the temperature goes down. The sensor reads resistance of thermostat as it varies and gives out its temperature reading.
Control voltage is varied from 0 to 15vdc and in return should produce variable resistance.
I know it won't output exact 0 ohms. it should produce 3k ohms-1M ohms versus 15VDC-0VDC or 28vdc - 0vdc.
Have anyone used Phillips Semiconductors N-channel field-effect transistor(PMBF4416)?
