An On–Off Mode RTD Oscillator Operating at Extremely Low Power Consumption

Abstract

A resonant tunneling diode (RTD)-based microwave on-off mode oscillator for on-off keying (OOK) transceiver applications operating at extremely low power consumption is proposed. In order to achieve the low-power operation, the negative differential conductance characteristic at a low-voltage arising from quantum effects of the RTD is used for RF signal generation. The fabricated integrated circuit of the RTD-based oscillator by using an InP-based RTD/heterojunction bipolar transistors quantum-effect IC technology shows low power consumption of 1.14 mW at an oscillation frequency of 5.725 GHz industrial, scientific, and medical band. The fabricated RTD-based oscillator operates in an on-off mode with a high data rate of 500 Mb/s. The obtained energy efficiency of 2.28 pJ/bit is found to be the best reported up to date.Index Terms-Microwave oscillators, negative resistance circuits, quantum effect semiconductor devices, resonant tunneling diode (RTD).

“…The multi-terminal devices based on NTC behavior have been heavily studied due to their potential applications in future electronic circuits, such as high-speed switching devices, high-frequency oscillators and memories [1][2][3][4][5]. Most of the reported NTC devices so far were inorganic semiconductor materials, including III-V semiconductors, Si-based materials and two-dimensional atomic crystals [6][7][8][9][10].…”
