METHOD AND SYSTEM FOR A RECEIVER WITH UNDERSAMPLING MIXING USING MULTIPLE CLOCK PHASES |
摘要 |
Methods and systems for a receiver with undersampling mixing using multiple clock phases are disclosed and may include undersampling a received wireless signal utilizing multiple undersamplers and clocking each of the undersamplers with a separate clock signal. Each of the clock signals may be at a sampling frequency but with a different phase angle. The difference of the phase angle between each of the clock signals may be adjusted and may be determined by the number of undersamplers. A gain ratio may be configured for two signals summed to generate each of the clock signals for the phase angle adjusting. The two signals may include in-phase and quadrature signals. Each of the summed signals may be normalized utilizing limiters. The sampling frequency may be an integer sub-harmonic of the received signal. The undersamplers may include track and hold or sample and hold circuits.
