Abstract—A variable-phase ring oscillator (VPRO) and
phase-locked loop (PLL) architecture is introduced for inte-
grated phased arrays. The architecture eliminates key building
blocks such as mixers, phase shifters and power splitters/com-
biners, allowing for compact and low-power implementations.
This paper presents the principles of operation of the architecture
in transmit and receive modes, along with a detailed theoret-
ical treatment of c
