Low-power/high-speed digital/analog ICs using an RTD-based MMIC technology (Electron devices: 第15回先端半導体デバイスの基礎と応用に関するアジア・太平洋ワークショップ(AWAD2007)) Low-Power/High-Speed Digital/Analog ICs using an RTD-based MMIC Technology

This paper describes the recent results on new types of High-Speed/Low-Power NDR (Negative Differential Resistance) ICs based on a monolithic quantum-effect device technology of RTD/HBT. As a representative digital IC, a low-power/high-speed MOBILE (MOnostable-BIstable transition Logic Element)-based D-flip flop IC is presented with the related frequency divider performance. The RTD-based D-flip flop IC demonstrated excellent speed performance at a significantly reduced dc power level. As an example of analog ICs, an RTD MMIC VCO with extremely low power consumption and good phase noise characteristics is presented and discussed. These results demonstrate the potential of RTD-based ICs to overcome the performance limitation of the conventional digital/analog IC topology.
