This letter presents the microwave performance of a sub-100 ??W Ku-band differential-mode resonant tunneling diode (RTD)-based voltage controlled oscillator (VCO) with an extremely low power consumption of 87 ??W using an InP-based RTD/HBT MMIC technology. In order to achieve the extremely low-power Ku-band RTD VCO, the device size of RTD is scaled down to 0.6 ?? 0.6 ??m2. The obtained dc power consumption...
This paper presents a K-band balanced RTD-based MMIC VCO with extremely low power consumption. In order to reduce the power consumption, an InP-based RTD is used for microwave power generation. The K-band VCO generates an RF output power of -17.7 dBm at a DC power of 1.0 mW. A wide tuning range of 2.1 GHz is obtained by using the base-collector junction of the integrated HBT as a varactor. In addition,...
