Goal
Traditional wireless circuits
Designed for worst case environmental variations
and
worst case process corners.
Involves significant built in design margin.
MotivationMotivation
Waste of performance (i.e. power) under favorable condition.
SAVE POWER by adapting to environment and process.

System in OperationSystem in Operation
Environment Adaptability allows transceiver operation with very less built in design margin. (i.e. Virtually Zero Margin) - Saves significant power under favorable environmental condition.
- 3X transmitter and 4X receiver power savings could be achieved.
Process Adaptability makes this adaptation near optimal even under process variation.
ConclusionConclusion
Significant increase in battery life.Significant increase in battery life.
