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.
