Abstract
Circuits, architectures, a system and methods for providing quadrature output signals. The circuit generally includes a quadrature signal generator and a plurality of frequency dividers. The plurality of frequency dividers are each configured to receive a plurality of quadrature signal generator outputs at a first frequency and provide a plurality of outputs at a second frequency. The method generally includes providing a plurality of quadrature signals at a first frequency and dividing the first frequency of the quadrature signals by n, wherein n is an odd integer of at least 3, thereby providing a plurality of divided-by-n quadrature outputs at a second frequency, wherein the second frequency is about equal to the first frequency divided by n. The present disclosure further advantageously improves quadrature signal generation accuracy, reliability and/or performance.
