  2. 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.

  3. Leeson's equation - Wikipedia

    en.wikipedia.org/wiki/Leeson's_equation

    Leeson's equation is an empirical expression that describes an oscillator's phase noise spectrum.. Leeson's expression [1] for single-sideband (SSB) phase noise in dBc/Hz (decibels relative to output level per hertz) and augmented for flicker noise: [2]

  4. Voltage-controlled oscillator - Wikipedia

    en.wikipedia.org/wiki/Voltage-controlled_oscillator

    VCOs can be generally categorized into two groups based on the type of waveform produced. [4]Linear or harmonic oscillators generate a sinusoidal waveform. Harmonic oscillators in electronics usually consist of a resonator with an amplifier that replaces the resonator losses (to prevent the amplitude from decaying) and isolates the resonator from the output (so the load does not affect the ...

  5. Cathode follower oscillator - Wikipedia

    en.wikipedia.org/wiki/Cathode_follower_oscillator

    The Cathode follower oscillator is an electronic oscillator circuit in which the oscillation frequency is determined by a tuned circuit consisting of capacitors and inductors, that is, an LC oscillator. [1] The circuit is also known as differential amplifier oscillator, emitter follower oscillator, source-coupled oscillator or Peltz oscillator.

  7. RC oscillator - Wikipedia

    en.wikipedia.org/wiki/RC_oscillator

    Another common design is the "Twin-T" oscillator as it uses two "T" RC circuits operated in parallel. One circuit is an R-C-R "T" which acts as a low-pass filter. The second circuit is a C-R-C "T" which operates as a high-pass filter. Together, these circuits form a bridge which is tuned at the desired frequency of oscillation.

  8. Phase-shift oscillator - Wikipedia

    en.wikipedia.org/wiki/Phase-shift_oscillator

    A phase-shift oscillator is a linear electronic oscillator circuit that produces a sine wave output. It consists of an inverting amplifier element such as a transistor or op amp with its output fed back to its input through a phase-shift network consisting of resistors and capacitors in a ladder network .

  9. Multivibrator - Wikipedia

    en.wikipedia.org/wiki/Multivibrator

    A vacuum tube Abraham-Bloch multivibrator oscillator, France, 1920 (small box, left).Its harmonics are being used to calibrate a wavemeter (center).. The first multivibrator circuit, the classic astable multivibrator oscillator (also called a plate-coupled multivibrator) was first described by Henri Abraham and Eugene Bloch in Publication 27 of the French Ministère de la Guerre, and in ...
