Abstract

This paper presents a low-power and a low-noise 30 GHz, sub-sampling phase-locked loop (SSPLL) with a 1° phase shift resolution for millimeter-wave phased arrays. Phase shifting is integrated into the PLL for low power consumption and operates at low frequencies. Using a two-point phase-shifting, the SSPLL achieves a high-resolution phase-shift with relaxed circuit complexity. Inductive coupling between the VCO and the feedback loop eliminates the VCO butter with minimal loading. Implemented in a standard 65 nm bulk-CMOS process, the VCO consumes 2.9 mW with a tuning range between 29. 3-31.2GHz. It dissipates 4.2 mW from a 1. 2V supply with a jitter of 105 fsec that achieves phase shift resolution of 1°, reference spur of -60dBc, and a PLL FoM of -253dB.
