    摘要: A method for receiver state estimation includes communicating, from a first communications device to a second communications device, a first plurality of wake-up frames; receiving, at the first communications device from the second communications device, an indication of a received wake-up frame of the communicated first plurality of wake-up frames; determining, by the first communications device, a time at which the second communications device is in a ready state based on the received indication; subsequently communicating, from the first communications device to the second communications device, a second plurality of wake-up frames. The first plurality is greater than the second plurality, the reduction in number from the first plurality to the second plurality being based on the determined time at which the second communications device is in a ready state.

    摘要: An output buffer provides a stable, predetermined low voltage differential over power supply, temperature, and process variations yet has a high speed of operation. More particularly, a data path of an output buffer includes an emitter-coupled differential amplifier followed by an output section of two level-shifting emitter followers. A predetermined operating current biases the differential amplifier for unsaturated operation and a reference current biases the output section for unsaturated operation. The data path remains unencumbered by compensation circuitry to preserve high speed operation. Instead, a voltage compensator biases the differential amplifier to compensate, at least in part, for variations in a supply voltage. In addition, a variable biasing current to the voltage compensator with a predetermined temperature coefficient may further temperature compensate the differential amplifier. In addition to such “upstream” compensation, the output buffer may further include “downstream” temperature compensation by the addition of a VBE multiplier circuit to the reference current biasing of the output section. Additional temperature and level-shifting compensation may also be achieved through cascading a plurality of buffer stages.
