  • Input Impedance
    Input impedance of an amplifier is the equivalent impedance that the signal input sees. Impedance (Z) is the resistance to alternating signal flow and is a result of the resistance, capacitance, and the inductance of the circuitry of a device. Input impedance is typically specified to be much
  • AN721: Impedance Matching Networks Applied to RF Power Transistors, Courtesy of Motorola
    be considered as a corollary of the matching circuit. Matching is necessary for the best possible energy transfer from stage to stage. In RF-power transistors the input impedance is of low value, decreasing as the power increases, or as the chip size becomes larger. This impedance must be matched
  • Input Voltage Standing Wave Ratio (VSWR)
    Input voltage standing wave ratio (VSWR), a unitless ratio ranging from 1 to infinity, expresses the amount of reflected energy at the input of the device. In a system, impedance mismatches cause some of the transmitted energy to be reflected back to its source. The frequency of the signal

  • Inductor-Based Step-Up Switching Regulators
    is located far away from the switching regulator or its input impedance is high, the PWM in the regulator increases the on time of the switching transistor to compensate for the voltage drop due to the internal impedance of the source or long power connection(s). The negative input resistance of any

    and condensation as well as the use of long connecting tubes and input filters.
  • Matching circuit optimization for antenna applications
    Impedance matching is an essential part of antenna design. The input impedance of an antenna needs to be reasonably close to the amplifier impedance (e.g. 50 Ohm), otherwise the signal is reflected back to the amplifier and not radiated by the antenna.
  • Single Supply Operation With Power Op Amps
    many of the characteristics of the ideal differential gain block of Figure A. The ideal differential gain block is characterized by infinite gain and bandwidth, infinite input impedance, zero output impedance and zero differential input error. These characteristics imply that the overall performance
