60‐GHz low‐power OOK transmitter in 65‐NMCMOS technology

Abstract

ABSTRACTThis article describes the design of a low‐power 60‐GHz OOK transmitter. A simple OOK structure is adopted for a low‐power and stable operation. The power consumption is reduced by implementing a LC‐VCO that operates at a low‐voltage. In addition, a switching modulator in the transmitter consumes less power due to no power consumption at the low‐state of a high‐speed data signal. The transmitter, implemented in a 65‐nm CMOS technology, has an output power of −2 dBm, on/off isolation over 40 dB, and tuning range of 64.8–67.7GHz. It is possible to communicate wirelessly within 5cm while consuming only 13.3 mW. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1977–1980, 2015
