In this second part of Paving the way for the next generation audio codec for True Wireless Stereo (TWS) applications whitepaper, energy efficiency will be discussed and several means to achieve extra-long playtime will be exposed.
The free lunch offered for decades by Moore’s law is now over and scaling down to the next technology node no longer offers the required energy efficiency gains. Design teams must now pursue their gains by deploying increasingly complex power management techniques to meet the demands of the new IoT markets.
This article presents the challenge of pairing an RF analog circuit with the appropriate inductor-based embedded Switching Regulator (namely eSR, equivalent to on-board DC/DC) allowing to meet both the power efficiency requirements and the module performance level at the same time.
