The main idea is that a fundamental 20 GHz signal and its sufficiently strong third harmonic at 60 GHz are generated simultaneously in a single oscillator. The desired 60 GHz local oscillator (LO) signal is delivered to the output, whereas the 20 GHz signal can be fed back for phase detection in a phase-locked loop. Third-harmonic boosting and extraction techniques are proposed and applied to the frequency generator. A prototype of the proposed frequency generator is implemented in digital 40 nm CMOS. It exhibits a PN of -100 dBc/Hz at 1 MHz offset from 57.8 GHz and provides 25% frequency tuning range (TR). The achieved figure-of-merit (FoM) is between 179 and 182 dBc/Hz. | Funding Details: | European Research Council | Type of material: | Journal Article | Publisher: | IEEE | Journal: | IEEE Journal of Solid-State Circuits | Volume: | 51 | Issue: | 5 | Start page: | 1261 | End page: | 1273 | Copyright (published version): | 2016 IEEE | Keywords: | PLL; 60 GHz; Frequency divider; Harmonic boosting; Harmonic extraction; Implicit multiplier; Mm-wave; Oscillator; Phase noise (PN); Transformer | DOI: | 10.1109/JSSC.2016.2528997 | Language: | en | Status of Item: | Peer reviewed |
