JFET
Why are they used?
JFETs the simplest type of field effect transistor. It can be used as an electronically-controlled switch or as a voltage-controlled resistance. There are 2 type JFET : n-channel JFETs. p-channel JFETs
Applications / How do you spot opportunities?
Application as:
- Displacement sensors
- High input impedance amplifiers
- Low-noise amplifiers
- Differential amplifiers
- Constant current sources
- Analogue switches or gates
- Voltage controlled resistors
How to ask for opportunities?
Do you need JFET as gate current, and cannot use MOSFET, because of the some low-noise, high input-impedance op-amps requirement?
