The resonant tunneling diode (rtd) belongs to the family of these diodes and is believed to be an element of a future low power, high density integrated circuit because of a possible ultra low power operation with a few electrons. Several researchers have already been reported different techniques of modelling and synthesis of diodes using.
To address these issues, we replace the microbolometer with a metal-oxide-metal tunnel diode [11,12]. Mom diodes exhibit high ir impedance and a non-linear current-voltage (i-v) characteristic, and thus are capable of rectifying high-frequency antenna currents at a localized point in the array.
Integrated tunnel diodes enable design options which can result in a decrease in power dissipation and an increase in speed and function per area. 1 since 1957, the tunnel diode has been widely investigated for high-speed circuit applications, due to its intrinsic high switching speed, and its “n-shaped” current- voltage (i−v.

Tunnel diodes are made from germanium or gallium arsenide due to their highest peak voltage to valley point swing. The ratio of high peak current to valley current quantifies the maximum voltage swing allowed in negative resistance region. Applications: tunnel diode can make a very stable oscillator circuit.
