Abstract:
A system and method quadrature clock generation circuit includes an approximate quadrature clock generator and an I/Q correction circuit. The approximate quadrature clock generator has an input configured to receive an input signal and generate an approximate quadrature clock and an approximate in-phase clock using the input signal. The I/Q correction circuit is configured to receive the approximate quadrature clock at a first quadrature input and the approximate in-phase clock at a first in-phase input and output an improved quadrature clock at a first quadrature output and improved in-phase clock at a first in-phase output.

Claim (Index 17):
A quadrature clock generation circuit comprising:\n an approximate quadrature clock generator configured to receive a forwarded clock from a channel and output an approximate in-phase clock; and at least one I/Q correction circuit connected to the approximate clock generator and configured to:\n receive the approximate in-phase clock and the approximate quadrature clock; \n shift the phase of each of the approximate in-phase clock and the approximate quadrature clock according to a reference phase shift; \n generate an improved quadrature clock by adding the phase shifted approximate in-phase clock with the approximate quadrature clock; \n generate an improved in-phase clock by subtracting the phase shifted approximate quadrature clock from the approximate in-phase clock; and \n output the improved quadrature clock and the improved in-phase clock.
