JFETs (junction field-effect transistors) can make low-noise high-impedance amplifiers that are better than any other technology. Like all things analog, they are not the best for everything, but you ...

Editor's note: Linear Integrated Systems co-founder, John H. Hall, is an industry veteran who is still hands on when it comes to innovations like the latest JFET, LSK489. Anyone using an electronic ...

Dipping into the Linear Integrated Systems website again, revealed another interesting app note on fet amplifier front-ends, written around the firm’s LSK489 monolithic dual low-noise n-fet. Called, ...

An N-channel JFET has a low bias current when its gate is biased negative to the source. However, this requires either that the gate voltage be biased negative with respect to the source voltage or ...

Someone has posted an excellent description of how differential pairs work – both bipolar and jfet. It seems to be the 11th chapter of a book, so I hope no one has had their copyright broken (a few ...

Figure 1 shows a benign means of interfacing a low-level, wideband differential signal to an analog-to-digital converter (ADC). The FET input stage (AD8066) draws only 6 pA of input bias current and ...
