The current from the bias battery V b biases the diode into the center of its curve (black), where it has a negative differential resistance of r (red). The operating point and output voltage of the circuit v o is at the intersection of the tunnel diode curve and the resistor load line R (blue) .Since R < r , if the two values are close in ...
A tunnel diode or Esaki diode is a type of semiconductor diode that has effectively "negative resistance" due to the quantum mechanical effect called tunneling. It was invented in August 1957 by Leo Esaki and Yuriko Kurose when working at Tokyo Tsushin Kogyo, now known as Sony .

English: A demonstration circuit showing how a tunnel diode can amplify a signal using negative differential resistance. The DC voltage V b biases the tunnel diode TD into its negative resistance region and also supplies the power used in amplifying the signal. For stability the resistor R must be less than the diodes negative resistance r.

The tunnel diode circuit (see diagram) is an example. [82] The tunnel diode TD has voltage controlled negative differential resistance. [54] The battery adds a constant voltage (bias) across the diode so it operates in its negative resistance range, and provides power to amplify the signal.
