    Colpitts oscillator: A new criterion of energy saving for high performance signal sources. US: Elsevier. The Colpitts circuit, like other LC oscillators, consists of a gain device such as a bipolar junction transistorfield-effect transistor, operational amplifier, or vacuum tube with its output connected to its input in a feedback loop containing a parallel LC circuit tuned circuitwhich functions as a bandpass filter to set the frequency of oscillation.

    In the Hartley circuit, oscillation is more likely for larger values of transconductance and larger values of inductance. As with any oscillator, the amplification of the active component should be marginally larger than the attenuation of the capacitive voltage divider, to obtain stable operation.

    The above analysis also describes the behavior of the Pierce oscillator.

    Electronic oscillators. The distinguishing feature of the Colpitts oscillator is that the feedback for the active device is taken from a voltage divider made of two capacitors in series across the inductor.

    An electrical dual of the standard Pierce oscillator using two inductors and one capacitor is equivalent to the Hartley oscillator.

    El oscilador Hartley es un circuito electrónico de alta frecuencia basado en un oscilador LC. Fue creado por el inventor Estadounidense Ralph. O circuito oscilador por deslocamento de fase possui 3 malhas RC cada No oscilador Colpitts, a impedância no circuito de realimentação é uma malha LC.

    Resumen de los osciladores LC. Lo que hacemos es usar un amplificador y un circuito tanque para realimentar una señal con la amplitud y.
    This assumes that the transistor does not saturate, the collector current flows in narrow pulses, and that the output voltage is sinusoidal low distortion.

    Colpitts[1] is one of a number of designs for LC oscillatorselectronic oscillators that use a combination of inductors L and capacitors C to produce an oscillation at a certain frequency. In other projects Wikimedia Commons.

    If the two capacitors are replaced by inductors, and magnetic coupling is ignored, the circuit becomes a Hartley oscillator. December

    RF Components and Circuits. Hay versiones militares de este integrado que llegan hasta 18 Voltios. This method will be used here to determine conditions of oscillation and the frequency of oscillation. If the impedance yields a negative resistance term, oscillation is possible. Para sustituirlos vamos a usar una red desfasadora formada por RC, es decir, resistencias y condensadores, como es el caso del ya mencionado oscilador en puente de Wien.

    Thus, a Colpitts oscillator used as a variable-frequency oscillator VFO performs best when a variable inductance is used for tuning, as opposed to tuning one of the two capacitors.

    Given all other values, the input resistance is roughly.

    This assumes that the transistor does not saturate, the collector current flows in narrow pulses, and that the output voltage is sinusoidal low distortion. Thus, a Colpitts oscillator used as a variable-frequency oscillator VFO performs best when a variable inductance is used for tuning, as opposed to tuning one of the two capacitors.
