| Keywords: Negative resistance oscillator.svg negative resistance electronic oscillator circuit which uses a one-port component with negative differential resistance such as a magnetron tube tunnel diode or Gunn diode to generate a sine wave signal It consists of a resonant circuit such as a tuned circuit cavity resonator or quartz crystal connected in series with the negative resistance A DC bias voltage V<sub>s</sub> which moves the operating point into the negative resistance region provides power for the circuit The negative resistance cancels the positive resistance in the resonant circuit creating a circuit without damping which generates spontaneous electrical oscillations at the resonant frequency of the tuned circuit Negative resistance oscillators like this are often used at microwave frequencies Circuits with N shaped voltage controlled negative resistance devices usually use this series connection Circuits with S shaped current controlled negative resistance devices are often connected in parallel 2012-07-09 own Chetvorno cc-zero Uploaded with UploadWizard Negative resistance Electronic oscillators Oscillator circuits | ||||
