Subtag of field-effect-transistor

Anything related to JFETs (Junction Field Effect Transistors) semiconductor devices, a particular type of field effect transistor.

They come in two varieties, N-channel and P-channel, whose behavior is specular wrt. the polarities of currents and voltages.

Q&A Are a JFET's Idss and Vgs(off) values correlated?

I know that many JFETs parameters have a very large manufacturing spread, in particular, $I_{DSS}$ and $V_{GS(off)}$, as one can see (for example) in this datasheet excerpt: ... My question i...

Q&A Choosing between common-drain JFET amplifier, and common-source

Do common-source JFET amplifiers have an advantage over common-drain? The JFET would be in a low noise photodiode amplifier. The signal is 100us pulses with 10us raise times. Here are the schema...

Q&A JFET equation of current

Is this equation valid only when a JFET in saturation mode , correct? because in the ohmic region the JFET acts like a voltage controlled resistor and increase in VDS increases the resistance of th...
