  • Patent number: 10911037
    Abstract: Embodiments described herein provide a system having phase synchronized local oscillator paths. The system includes a first circuit, which in turn includes a first counter configured to generate a first counter output signal in response to a first clock signal controlling the first counter. The first circuit also includes a first phase-locked loop coupled to the first counter. The first phase-locked loop is configured to receive the first counter output signal as a first synchronization clock for the first phase-locked loop and to generate a first output signal having rising edges aligned according to the first counter output signal.

  • Patent number: 10187082
    Abstract: Embodiments described herein provide a method for correcting a propagation delay induced error in an output of an asynchronous counter. An input clock is applied to the asynchronous counter. A gray-code count is generated by the asynchronous counter. The gray-code count is mapped to a binary count. An error component, indicative of a counting error induced by a propagation delay between the input clock and the binary count, is generated by taking an exclusive-OR operation over the gray-code count and the input clock. The error component is added to the binary count to generate an error-corrected binary count. The error-corrected binary count is output.

  • Patent number: 9160489
    Abstract: Systems and methods associated with origin dodging for a transmitted signal are described. One method includes receiving a transmission sequence for transmission to a receiver. The transmission sequence includes a sequence of transmit symbols and each transmit symbol corresponds to a coordinate pair positioning the transmit symbol's phase on an I-Q plane. The method includes sampling and filtering the transmission sequence to create transition samples and determining whether any transition sample is within a predetermined radius of an origin of the I-Q plane. When a transition sample is positioned within the radius, the method includes generating a dodging symbol and inserting the dodging symbol into the transmission sequence to create a modified transmission sequence. A filtered signal that includes filtered samples of the modified transmission sequence is provided.
