    Study Notes

    Diodes and Amplifiers

    • A diode clamper shifts the dc level of a signal, adding a dc component to the signal.
    • The average voltage for a pure sinusoidal full waveform is zero.

    Diode Characteristics

    • In an ordinary diode, as the reverse voltage (Vr) is continuously increased in reverse bias mode, the reverse current remains very small until the reverse breakdown voltage is reached.
    • Beyond the reverse breakdown voltage, the reverse current increases rapidly.

    Amplifier Configurations

    • In a common collector configuration, the input signal is applied to the base and the output is taken from the emitter.
    • The phase relation between input and output in a common emitter amplifier is 0° or 360° (in phase).
    • In a common collector configuration, the input signal is applied to the base and the output is taken from the emitter.

    FETs vs BJTs

    • The main advantage of FETs over BJTs is their low power consumption and high input impedance.

    Limiters

    • A positive limiter removes the part of a signal above a certain level, limiting the signal amplitude.
    • The function of a positive limiter in a circuit is to limit the signal amplitude.

    Diode Clamper

    • A diode clamper shifts the dc level of a signal, adding a dc component to the signal.
    • The purpose of a diode clamper in a circuit is to add a dc component to a signal, shifting its dc level.
