    摘要： A wireless communication device includes an antenna array with multiple antenna elements, an array of power amplifiers, and an array of phase shifters. Each antenna element is coupled to a power amplifier and a phase shifter. The device also includes transmitter circuitry coupled to the antenna array to encode a constant amplitude signal, which includes a power amplifier enable code to indicate which power amplifiers are to run in a subsequent data sample and a beam direction code to control beam direction of each phase shifter of the array of phase shifters in the subsequent data sample. The constant amplitude signal is then provided to the array of antenna elements and amplitude and phase modulation is combined over an air interface into a composite modulated signal.

    摘要： Disclosed is a method and apparatus to extend TDC resolution to better than 1 ps without incurring a matching and power penalty. Higher resolution can be achieved by segmenting the resolution between a mismatch free re-circulating time-to-digital converter (RTDC) and a stochastic time-to-digital converter (STDC). The disclosed RTDC replicates the same delay element to eliminate mismatch with the required dynamic range (200 ps for a 5 GHz example) and moderate resolution (3-5 ps typical corresponding to 6-7 bits for the 5 GHz case). While the STDC can achieve a resolution of 50 fs but with a range of only 3-5 ps which also corresponds to approximately 6-7 additional bits by exploiting process variations and mismatch to achieve a very fine resolution with limited dynamic range.
