Abstract
Embodiments of the invention comprise methods, apparatuses and systems for a dynamic bias control circuit configured to dynamically bias an amplifier. The dynamic bias control circuitry includes four branches. Each of the four branches includes a transistor operably coupled in series between a current source and a reference voltage. Each branch also includes a storage element having a first terminal and a second terminal and configured for selectively coupling the first terminal to the reference voltage, selectively coupling the first terminal to a node located between the current source and a drain of the transistor, selectively coupling the second terminal to the node, and selectively coupling the second terminal to an output.
