  • Single Supply Operation With Power Op Amps
    The article outlines the problems and solutions for operating power op amps with a single high power supply voltage. Several application circuits are proposed that may help the user reduce system costs while maintaining high performance. Some familiarity with op amp circuits is assumed. Although
  • AN721: Impedance Matching Networks Applied to RF Power Transistors, Courtesy of Motorola
    Some graphic and numerical methods of impedance matching will be reviewed here. The examples given will refer to high frequency power amplifiers. Although matching networks normally take the form of filters and therefore are also useful to provide frequency discrimination, this aspect will only
  • Dewar-to-Dewar Data Transfer at 2 Gigabits per Second
    Josephsoii digital. circuits can be integrated into inultichip digital subsystems. that can pass data at high rates without the use of power-. hungry semiconductor amplifiers.
