Abstract:
A method that calibrates a device for echo cancellation and a device with calibration for echo cancellation are provided. Devices may be calibrated such that the echo residual error is less than a threshold determined by the calibration accuracy. Non-ideal factors such as mismatch may be eliminated during calibration.

Abstract:
Embodiments of the invention are generally directed to a linear regulator with improved power supply ripple rejection. An embodiment of an apparatus includes an linear regulator to receive a system power supply and to generate a regulated power supply; a first voltage reference generator to generate a first voltage reference for the linear regulator; a second voltage reference generator to generate a second voltage reference for the linear regulator; and a voltage reference and power switcher. In some embodiments, the voltage reference and power switcher is to switch a voltage reference for the linear regulator from the first voltage reference to the second voltage reference and is to switch a part of a power supply for the linear regulator from the system power supply to the regulated power supply.

Embodiments of the invention are generally directed to a line driver with separate pre-driver for feed-through capacitance. An embodiment of an apparatus includes a differential pair of transistors to generate an output signal on a first output node and a second output node; a pass-through capacitance coupled with the first output node and the second output node; a first pre-driver to drive an input signal for the differential transistors; and a second pre-driver to drive the input signal for the pass-through capacitance.
