Abstract: An apparatus for providing fast-settling quadrature detection and correction includes: a quadrature correction circuit that receives four quadrature clock signals; a quadrature detector that selects two clock signals among the four quadrature clock signals; and a phase digitizer that generates a digital code indicating a phase difference between the two clock signals. The quadrature correction circuit adjusts a phase between the two clock signals using the digital code.

Abstract: A synchronized I/Q detection circuit is provided. A first subset of input signals and, subsequently, a second subset of input signals are provided by a first multiplexer and received by a first phase detector. Outputs of the first phase detector are receiving, by a first reset and sampling circuit. A second set of input signals are provided by a second multiplexer and received by a second phase detector, from a second multiplexer, while the first multiplexer receives the first and second subsets of input signals. The first subset of input signals has a same phase order as the second set of input signals, and the second subset of input signals has a different phase order than the second set of input signals. Outputs of the second phase detector are received by a second reset and sampling circuit. A comparator outputs a detected phase difference based on the outputs of the first and second reset and sampling circuits.
