Design and optimization of a 94GHz rotary traveling wave oscillator for mm-wave applications

In this work, the design of a 94GHz rotary traveling wave oscillator (RTWO) is presented. The oscillator targets mm-Wave transceivers for biomedical imaging applications. A design procedure to minimize the total power consumption is presented. Using this proposed procedure, a 4 section RTWO is designed in a 65nm CMOS technology. The oscillator consumes 80mA (including buffers) from a 1V supply, and has a phase noise of −106.4dBc/Hz at 10MHz offset with a total core area of 0.36mm2.
