  2. Blocking oscillator - Wikipedia

    en.wikipedia.org/wiki/Blocking_oscillator

    In some designs (as shown in the diagrams) the secondary voltage V s adds to the source voltage V b; in this case because the voltage across the primary (during the time the switch is closed) is approximately V b, V s = (N+1)×V b. Alternately the switch may get some of its control voltage or current directly from V b and the rest from the ...

    en.wikipedia.org/wiki/File:Oscillator_block...

    English: Abstract block diagram of an electronic oscillator. It consists of an amplifying element with transfer function G(jω) with its output fed back into it's input through a feedback network with transfer function H(jω). The output voltage is labelled V o and the feedback voltage is labelled V f.

  4. File:Oscillator diagram2.svg - Wikipedia

    en.wikipedia.org/wiki/File:Oscillator_diagram2.svg

    English: Block diagram of an electronic oscillator circuit, with the feedback loop broken to show how to calculate the loop gain. It consists of an amplifier element with amplification A, with its output V o fed back into its input V i through a feedback network with transfer function β(jω).

  5. Barkhausen stability criterion - Wikipedia

    en.wikipedia.org/wiki/Barkhausen_stability_criterion

    Block diagram of a feedback oscillator circuit to which the Barkhausen criterion applies. It consists of an amplifying element A whose output v o is fed back into its input v f through a feedback network β(jω). To find the loop gain, the feedback loop is considered broken at some point and the output v o for a given input v i is calculated:

  6. File:Negative resistance oscillator block diagram.svg

    en.wikipedia.org/wiki/File:Negative_resistance...

    English: Block diagram of a negative resistance electronic oscillator, illustrating the "reference plane" analysis method. The circuit consists of a differential negative resistance device such as a Gunn diode or magnetron tube connected to a resonator such as a LC circuit , dielectric resonator , or cavity resonator .

  7. Frequency synthesizer - Wikipedia

    en.wikipedia.org/wiki/Frequency_synthesizer

    Block diagram of a common type of PLL synthesizer. The key to the ability of a frequency synthesizer to generate multiple frequencies is the divider placed between the output and the feedback input. This is usually in the form of a digital counter , with the output signal acting as a clock signal .

  9. Electronic oscillator - Wikipedia

    en.wikipedia.org/wiki/Electronic_oscillator

    Simple relaxation oscillator made by feeding back an inverting Schmitt trigger's output voltage through a RC network to its input.. An electronic oscillator is an electronic circuit that produces a periodic, oscillating or alternating current (AC) signal, usually a sine wave, square wave or a triangle wave, [1] [2] [3] powered by a direct current (DC) source.
