Abstract :
A low power on-off mode resonant tunneling diode (RTD) based oscillator is demonstrated by using an RTD/heterojunction bipolar transistor (HBT) MMIC technology. Using the negative differential resistance (NDR) characteristics of the tunneling diode, which arise at a low applied voltage range from the quantum-effect, the low power oscillators are used for microwave on-off keying (OOK) signal modulation. The fabricated RTD-based oscillator shows low power consumption of 5 mW at an oscillation frequency of 5.2 GHz. The RTD-based oscillator operates in an on-off mode with a high data rate of 1 Gb/s from the fast switching capabilities of the RTD and HBT switch. A good energy efficiency of 5 pJ/bit has been obtained in this work.
