Abstract: Implementations of a pre-emphasis signal processing system may include an output driver which may include a pre-emphasis transistor coupled with a steady state transistor, where gates of the pre-emphasis transistor and steady state transistor may be coupled together. The system may include a regulator voltage input coupled to a source of the pre-emphasis transistor; a first resistor coupled between a drain of the pre-emphasis transistor and an output of the output driver; and a second resistor coupled between the drain of the steady state transistor and the output of the output driver; and a pre-emphasis source including a current source coupled to a delay transistor, the delay transistor coupled with the output of the output driver.

Abstract: Various embodiments of the present technology may provide methods and apparatus for an interface having a first bi-directional channel and a second bi-directional channel. The interface operates in one of a first operational state and a second operational state, and performs an exemplary power-saving scheme if it is operating in the second operational state. The interface may detect a plurality of power states and initiate the power-saving scheme based on the detected power state. The plurality of power states may comprise a first power state (low current mode), a second power state (high current mode), and a third power state (mid-current mode).

Abstract: Interface circuit. Example interface circuits may be used for data transfer in accordance with the USB protocol version 3.2 or higher. Example interface circuits are configured to enable cooperation with a sink device and/or a host device having a lower supply voltage than the interface circuit, and reducing or preventing voltage spikes herein after power-on reset (POR) events. Thereto, the detection circuit for detection of a sink device downstream of the interface circuit is provided with a signal path for use during a first period after the POR event and having a resistance larger than a resistance used during detection of the said sink device.

Abstract: Various embodiments of the present technology may comprise methods and system for a resettable flip flop. The flip flop may receive a clock signal along a first circuit path and a reset signal along a second circuit path. The first circuit path provides a first high voltage value and a first low voltage value, and the second circuit path provides a second high voltage value that is greater than the first high voltage value and a second low voltage value that is less than the first low voltage value.
