  • Solving the Noise Puzzle with Low-Noise Matched Bipolar Transistor Pairs
    Noise is one of the more important aspects of circuit design. Lower noise in audio amplifier design means better quality audio. Low-noise in instrument design means more reliable and accurate measurements at lower voltage and current levels. And low-noise in current source designs means less noise
  • A Guide to Using FETS (Field Effect Transistors) for Sensor Applications
    FETs (Field Effect Transistors). suitable for use in low noise amplifier applications for. photo diodes, accelerometers, transducers, and other types of sensors. Read the White Paper
  • A Guide to Using FETS for Sensor Applications
    In particular, low noise JFETs exhibit low input gate currents that are desirable when working with high impedance devices at the input or with high value feedback resistors (e.g., >=1M ). Operational amplifiers (op amps) with bipolar transistor input stages have much higher input noise currents
  • Understanding the Phenomenon of High-Power Pulse Recovery in GaN LNAs
    The Gallium Nitride (GaN) high electron mobility. transistor (HEMT) is well known for its use in microwave and millimeter wave power amplifiers due to its high breakdown voltage and ability to handle high RF power. Recently, GaN technology has also been used to create low noise amplifiers (LNAs
  • AN3010: An Examination of Recovery Time of an Integrated Limiter/LNA
    or nuclear electromagnetic pulse. Especially, low noise amplifiers (LNAs) in the front-end of microwave systems need high power protection because these amplifiers can sustain only low input power levels in the range of 10-20 dBm continuous wave (CW). To protect these circuits and maintain low
  • Linear Voltage Fan Speed Control Using Microchip's TC64X Family
    Pulse Width Modulation (PWM) fan speed control methodology pulse-width modulates a fan's full-rated power supply voltage at a low frequency, typically 30 Hz. A typical PWM circuit, consisting of a transistor in series with a fan, can be small and inexpensive because it is either fully
