  • Operation of 3- and 4- Terminal JFET
    A junction gate field-effect transistor (JFET) is the simplest. type of field effect transistor. This device can be used as an. electronically-controlled switch or as a voltage-controlled. resistor. In a JFET, current flows through a semiconducting. channel between the "drain" terminal
  • JFET Application Note: Reset Transistor
    In JFETs designed primarily for silicon drift detectors and Si(Li) detectors,. the reset transistor is configured as shown in Figure 1, with the base. shorted to the source, the collector shorted to the gate, and the emitter. connected to the reset pad. Since the gate-source JFET junction
  • JFETs The New Frontier Part 1, by Erno Borbely
    Welcome to a new era in audio amplification where JFETs rule. This noted designer champions their use to produce the best sound in your audio amp circuits.
  • Distortion and Source Impedance in JFET-input Op Amps
    of two JFET-input op amps for high and low source impedance. A new fabrication process that limits common mode capacitance provides more device options when low distortion is required over a wide range of source impedance.
  • LSK389 Dual Monolithic JFET for Ultra-Low Noise Applications
    The LSK389 is the industry 's lowest noise Dual N-Channel JFET, 100% tested, guaranteed to meet 1/f and broadband noise specifications, while eliminating burst (RTN or popcorn) noise entirely. The product displays high transconductance and very good matching. It is the JFET of choice for low noise
  • LSK489 Ultra Low Noise JFET
    For circuits designed to work with high impedance sources, ranging from electrometers to microphone preamplifiers, the use of a low-noise, high-impedance device between the input and the op amp is needed in order to optimize performance.
  • LSJ689 Ultra Low Noise P-Channel Dual JFET
    The dual monolithic P-channel LSJ689 is the complement to the N-channel LSK489. Both devices feature low offset, low noise and low capacitance. They enable the efficient implementation of fully complementary input stages without many of the device matching requirements when pairs of discrete devices
  • Consider the Discrete JFET When You Have a Priority Performance Objective
    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.
