Abstract:
Certain aspects of the present disclosure generally relate to techniques and circuits for phase correction, or at least adjustment, of multiple local-oscillator (LO) signals. For example, certain aspects provide an apparatus for phase adjustment. The apparatus generally includes a phase-locked loop (PLL), at least one frequency divider coupled to an output of the PLL, the at least one first frequency divider being external to the PLL, a phase adjustment circuit having an input coupled to an output of the frequency divider, and at least one mixer having an input coupled to at least one output of the phase adjustment circuit.
