Abstract
In this paper, a fully integrated 7–9 GHz ultra-wideband (UWB) radar IC is implemented in 0.13 μm CMOS technology. For high-resolution and long-range detection, the conventional equivalent time sampling method and the local oscillator correlation receiver are used. The switching of transmitter circuitry significantly reduces power consumption. A Tx to Rx loop-back test ensures that the detection range is up to 5.6 m and that the sensitivity is -81 dBm. The actual experiments with the antenna agree well with our prediction. The chip size is 2.8 mm × 2 mm, and the current consumption is 110 mW at 1.2 V.
期刊介绍：
The Journal of Electromagnetic Engineering and Science (JEES) is an official English-language journal of the Korean Institute of Electromagnetic and Science (KIEES). This journal was launched in 2001 and has been published quarterly since 2003. It is currently registered with the National Research Foundation of Korea and also indexed in Scopus, CrossRef and EBSCO, DOI/Crossref, Google Scholar and Web of Science Core Collection as Emerging Sources Citation Index(ESCI) Journal. The objective of JEES is to publish academic as well as industrial research results and discoveries in electromagnetic engineering and science. The particular scope of the journal includes electromagnetic field theory and its applications: High frequency components, circuits, and systems, Antennas, smart phones, and radars, Electromagnetic wave environments, Relevant industrial developments.
