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 ...
Another type of tunnel diode is a metal-insulator-insulator-metal (MIIM) diode, where an additional insulator layer allows "step tunneling" for more precise control of the diode. [11] There is also a metal-insulator-metal (MIM) diode, but due to inherent sensitivities, its present application appears to be limited to research environments.
An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...

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.
Bridge rectifier (four diodes in a package) often changed to "D" for diode BT, BAT: Battery or battery holder: often shortened to "B" C: Capacitor: CB: Circuit breaker: CN: Capacitor network: may be simplified to "C" for capacitor D, CR: Diode (all types, including LED), thyristor "D" is preferred for various types of diodes DL: Delay line: DN ...
