Abstract

One embodiment of the present invention features a poly-phase local oscillator generator combining frequency dividers and direct-injection-locked phase correctors. The poly-phase local oscillator generator comprises a plurality of phase correctors configured to relax frequency and tuning range of a reference local oscillator (LO), and a plurality of frequency dividers, coupled to the phase correctors, configured to offer different frequency segments. The phase correctors are expandable, so that phase accuracy can be optimized by cascading more of themselves.
