Abstract
Abstract The driving power of the local oscillator (LO) determines whether the mixers can work in an optimal state. Implementing high-power LO sources is challenging for transceivers in the terahertz band beyond 100 GHz. In this paper, a cross-coupled oscillator based on Cascode amplifiers is proposed. Using the principle of current-reuse, a high-power doubler-embedded cross-coupled local oscillator is designed by combing a frequency doubler and a cross-coupled oscillator. The circuit is processed by 55-nm CMOS technology. With a supply voltage of 1.6 V, the output power reaches −1.3 dBm at 156 GHz, and the DC-to-RF efficiency is 2.1%. In addition, this local oscillator has been used in an up-conversion mixer.
期刊介绍：
Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal.
Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies.
RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
