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 ...
When a JFET preamplifier with even lower noise is required, a discrete input device is the only solution. While the variety of JFETs on the market is shrinking year after year, some devices with an ...
