Classification: CPC H  G | IPC G  H

Claim 0:
1. A local oscillator (LO) signal generator, comprising:
a delay-locked loop (DLL) configured to generate, from an input signal having an input signal frequency that is a fraction of an output signal frequency, a set of phase-shifted input signals at the input signal frequency;
phase configuration circuitry coupled to the DLL, the phase configuration circuitry being configured to output a subset of phase-shifted signals from among the set of phase-shifted input signals; and
an injection locked clock multiplier (ILCM) configured to receive the subset of the phase-shifted signals as injected inputs, and to combine and frequency-multiply the subset of the phase-shifted signals to generate a set of LO signals at the output signal frequency,
wherein the subset of the phase-shifted signals have pane equally-spaced phase-shift with respect to another that is a fraction of a full clock cycle, the fraction of the full is cycle being equal to the fraction of the output signal frequency.
