Universal asymmetry compensation for packet timing protocols
The notion of a “PTP aware” path is one current proposed approach to reduce asymmetry effects. In a fully PTP aware path there is the notion of on-path support mechanisms such as boundary clocks and transparent clocks at every switching or routing node. However, on-path support methods only address time-transfer errors introduced inside network elements and any asymmetry in the transmission medium, such as, for example, the fiber strands for the two directions of transmission, cannot be compensated for by on-path support mechanisms. Furthermore, in a real operational network, which may traverse different operational domains administered by different entities, full on-path support is a difficult challenge. In certain managed network scenarios full on-path support can be contemplated. Nevertheless, the universal asymmetry compensation method described herein mitigates the asymmetry in a network path, without requiring on-path support mechanisms such as transparent clocks and boundary clocks. |

Trace canceller with equalizer adjusted for trace length driving variable-gain amplifier with automatic gain control loop
Distortions of both amplitude and phase along a transmission line are compensated for by a trace canceller inserted between a transmitter and a receiver. The trace canceller has an equalizer that compensates for a trace length between the transmitter and the trace canceller. A variable gain amplifier between the equalizer and an output buffer has its gain controlled by an automatic gain control circuit that compares low-frequency swings of the input and output of the trace canceller. The gain of the variable gain amplifier is reduced to prevent the output buffer from saturating and clipping peak voltages on its output. Thus both the variable gain amplifier and the output buffer remain in the linear region. Training pulses from the transmitter are passed through the trace canceller without clipping of peak voltages, allowing the transmitter and receiver to adjust transmission parameters to best match the transmission line. |

An example power supply includes an energy transfer element, a switch, and a controller. The switch is coupled to the energy transfer element to control a transfer of energy from an input to a galvanically isolated output of the power supply. The controller includes a delayed ramp generator, an integrator, an arithmetic operator, and a drive signal generator. The integrator generates a first signal responsive to integrating an input current of the power supply. The arithmetic operator generates a second signal responsive to the first signal and responsive to a ratio of a rectified input voltage to a dc output voltage of the power supply. The drive signal generator generates a drive signal in response to a delayed ramp signal and the second signal to control switching of the switch to provide power factor correction of the power supply and to provide a regulated current at the output. |

Switched mode power supply
A power supply having over power protection based on the same signal as used by the feedback path for controlling the switching of the power supply is disclosed. This means that no additional signal needs to be supplied to the control circuit to implement mains over protection. |
