Abstract
An adaptive bias module architecture and related methods is presented. According to one embodiment, for example, a method is presented comprising detecting a power level associated with data received by a transmit driver for transmission into an inductive load without analyzing the data content, and adapting a bias level applied to the transmit driver to facilitate transmission of the received data based, at least in part, on the detected power level.
Claims20
A method comprising:
- detecting a power level associated with data received by a transmit driver for transmission without analyzing data content;
- and
- adapting a cumulative bias level applied to the transmit driver to facilitate transmission of the received data based, at least in part, on the detected power level.
An apparatus comprising:
- a transmit driver, to provide an indication of power associated with transmission of a received set of data without analyzing content of the data itself;
- and
- an adaptive bias module, coupled to the transmit driver, to adjust a bias level applied to the transmit driver to facilitate transmission of the received data based, at least in part, on the received indication.
A machine accessible storage medium comprising:
- a plurality of executable instructions which, when executed, cause accessing machine(s) to implement an adaptive bias module, the adaptive bias module comprising a transconductance cell coupled to a threshold detector, wherein the threshold detector selectively supplements a bias voltage applied to the transconductance cell to drive a coupled transmit driver based, at least in part, on data received for transmission at the transmit driver, wherein the supplemental voltage temporarily increases the power applied to the transmit driver to facilitate transmission of received data.
