Abstract

An Esaki tunnel diode E is connected in series with an anti-resonant tuned circuit, L and C, and a load resistor RL. These are so chosen that transition between two static current levels of the diode E occurs after an integral number of cycles of alternating drive signal to provide a subharmonic oscillator.

Subharmonic Oscillator

An Esaki tunnel diode E is connected in series with an anti-resonant tuned circuit, L and C, and a load resistor RL. These are so chosen that transition between two static current levels of the diode E occurs after an integral number of cycles of alternating drive signal to provide a subharmonic oscillator.

The diode E is biased by battery B to provide stable operation of E at points P and Q on its characteristic curve 10. The LC combination is tuned at near a desired subharmonic frequency and prevents source G signals from switching the diode E at the input frequency but allows the diode E to switch at the desired subharmonic.
