  • Electronics for Guitarists
    Electronically variable resistors , called optocouplers or sometimes photocouplers, are ideally suited for the phase shifter application.

  • Implementation of an analogue model of a memristor based on a light-dependent resistor
    From the structure and operating principles, it can be seen that the optocoupler acts as a remotely controlled variable resistor in the circuit.
  • Current Equalization in Photovoltaic Strings With Module Integrated Ground-Isolated Switched Capacitor DC–DC Converters
    The drive to the output switch SSC and the voltage variable resistor in unit T from the CPU are also through optocouplers .

    It also eliminates the traditional optocoupler ’s CTR varia- tions with power supply and voltage, and the need to suffer the additional voltage drop of a series resistor .
  • Memristor Networks
    The float- ing memristor can be emulated most conveniently via a floating two-terminal de- vice with variable resistance, for example the digital potentiometer [6] or the light- dependent resistor (LDR) as a part of the optocoupler [3, 4].
