Abstract: A serial data receiver is disclosed. In one embodiment, a receiver includes an amplifier circuit configured to receive one or more signals that encode a serial data stream that includes a plurality of data symbols and to perform a comparison of the one or more signals to a threshold value to generate a recovered data symbol. The receiver circuit further includes a threshold circuit configured to generate a delayed version of the one or more signals. The threshold circuit is further configured to generate a delayed data symbol using the delayed version of the one or more signals and adjust the threshold value using the delayed data symbol.

Abstract: Provided herein are approaches for controlling remote slave DLL circuits with a master DLL circuit by conveying a relevant bias signal as a current signal instead of as a voltage signal.

Abstract: Disclosed herein is a wake-up circuit for a bias input of a circuit such as a slave DLL circuit, to allow it to be placed in a reduced power mode and be “awoken” (brought up to a control bias level) in a sufficiently small enough amount of time. The wake-up circuit couples a bias input node to a voltage level that is higher then the control bias level in response to a wake-up event, and then it couples the control bias node to the bias input node in response to their voltage levels being sufficiently close to one another.
