< Back Consider the JFET Introduction Though not as well known as the bipolar transistor or op amp, this long-established transistor still excels in where you need to optimize circuit behavior, such as for lowest noise. Many engineers are somewhat familiar with discrete bipolar transistors, such as the venerable 2N2222. They are also comfortable with the MOSFET (metal-oxide semiconductor field-effect transistor) as a discrete device for amplifying analog signals and switching power signals, as well as its role as the key digital structural element in large-scale ICs. But alongside these devices is the JFET (junction field-effect transistor), which was developed soon after the bipolar transistor. To many designers, the JFET is the nearly ideal three-terminal solid-state device, and its operation and parameters are analogous to the vacuum-tube triode. The difference is that the JFET is, of course, a low-voltage, much-more efficient device, although it can't deliver the power that a vacuum tube can. For applications which require extremely low noise, the JFET is often offers superior performance compared to any other discrete device, as well as op amps. Read More

< Back Military Sensors White Paper Linear Systems Mar 17, 2023 Linear Systems' White Paper Describes Lowest Noise Amplification for Sensor Signal Chains FREMONT, Calif., May 27, 2021 /PRNewswire/ -- Linear Systems, a world class producer of ultra low noise JFETS and semiconductors, has released an application note on creating low-noise signal chains for military sensors. The paper, "Military Higher-Performance Sensor Signal Chains," offers engineers solutions using ultra-low-noise discrete components added to an IC-based circuit to produce the better-performing signal chains in sensitive applications. Included are key applications with reference designs such as: Piezoelectric Element Preamps; Hydrophones; Accelerometers; Photodiode Preamps; and other types of sensors where discrete components are uniquely capable of performing critical initial amplification of sensor signals. "Better sensor systems enable earlier threat detection and more effective countermeasures, " Mr. Tim McCune said. "Our ultra-low-noise JFETS enable designers to build more sensitivity and capability into their sensor systems. This improved capability translates directly into greater value to the end users of these sensors." Linear Systems is a designer, manufacturer and seller of precision, high-performance, small-signal discrete semiconductors. A Silicon Valley company founded in 1987, it produces ultra-low-noise, monolithic dual and single JFETs and bipolar transistors, along with high-speed DMOS switches, small-signal MOSFETs, ultra-low leakage diodes and BiFET amplifiers.
