  • Publication number: 20210083836
    Abstract: A receiver circuit includes a clock lane propagating a clock signal. A self-sampled clock applies a delayed version of the clock signal to the clock signal and compensation logic controls an amount of delay of the delayed version of the clock, based on a reference voltage offset (difference) between the receiver and a transmitter. The delayed version of the clock is centered on one unit interval of the clock. An offset correction based on a clock duty cycle error is applied to data receiver front ends.

The delayed version of the clock is centered on one unit interval of the clock. An offset correction is computed as a global offset value based on a clock duty cycle error, combined with a local offset value for each data lane, and is applied to data receiver front ends.

  • Patent number: 10845834
    Abstract: A linear regulator for applications with low area constraint resulting in limited load decoupling capacitance that introduces a compensating zero in the regulator loop to counteract the loss of phase margin and further introduces a feed-forward noise cancellation path operating over a wide frequency range covering a first package resonance frequency. The feed-forward path has low power consumption and improves the power-supply rejection ratio.

  • Patent number: 10769517
    Abstract: According to some embodiments, the present disclosure may relate to a method of neural network analysis that includes receiving a first electronic message, storing it in a storage device, and decoding it to output a first data structure. The first electronic message may reference a first dictionary entry correlating the first electronic message to the first data structure including more bits than the first message. The method may also include providing the first data structure to a processing element to perform a data structure analysis on the first data structure yielding a second data structure including more bits than the first electronic message. The method may also include matching the second data structure to a second dictionary entry correlating the second data structure to a second electronic message that includes fewer bits than the second data structure, and transmitting the second electronic message instead of the second data structure.

  • Patent number: 10476537
    Abstract: A single-ended signal transmission system recovers a noise signal associated with a data input signal and uses the recovered noise signal to compensate for noise on the data input signal. The noise signal may be recovered from a noise reference signal line, or clock signal line, or a data signal line associated with a DC-balanced data input signal. The recovered noise signal may be represented as an analog signal or a digital signal. The recovered noise signal may be processed to compensate for DC offset and nonlinearities associated with one or more different input buffers. In one embodiment, the recovered noise signal includes frequency content substantially below a fundamental frequency for data transmission through the data input signal.

  • Patent number: 10298422
    Abstract: A multi-stage amplifier circuit equalizes an input signal through multiple signal amplification paths. DC gain is kept substantially constant over frequency, while adjustable high-frequency gain provides equalization (e.g., peaking). Various embodiments include a common source topology, a common gate topology, differential signaling topologies, and a topology suitable for stabilizing a voltage supply against high-frequency transient loads. A system may include one or more integrated circuits that may each include one or more instances of the multi-stage amplifier.

  • Publication number: 20180062978
    Abstract: A method may include hardwiring: a first dynamic input of M slices in a section of a sliced architecture to receive a main data sample; and a second dynamic input of each of X and Y slices to respectively receive a first or second delayed data sample, X, Y being subsets of M. A slice current may be multiplied with: the data sample in each of A of the M slices; and the first delayed data sample in each of B of the X slices. The method may also include summing: outputs of the A slices to obtain a weighted output current of the data sample; outputs of the B slices to obtain a weighted output current of the first delayed data sample; and the weighted output currents of the main data sample and of the first delayed data sample to obtain a net weighted output current of the section.
