Abstract
Various embodiments of the present invention relate to systems, devices and method of frequency synthesis that generate in-phase and quadrature-phase clock signals at a programmable frequency. The generated frequency, which can range from a fraction to multiples of the input reference frequency, is generated by dividers following a phase-locked loop, thus avoiding the use of a low input reference frequency as well as frequency doubling.
