Overview
SoC integrators targeting portable audio applications such as Smart Phones, PMP, PDA should demonstrate optimal recording performances as well as the best sound quality, while starring the longest playback capability.
shCOD95.BT01-Helium, the ultra low power audio CODEC, is thus the best ally of SoC integrators targeting such high volume markets. Its small area ensures a cost-effective SoC integration both in mature and very advanced pure logic processes.
This complete configuration of audio converter proves it feasible to combine Class-AB amplifiers, known for offering the lowest Bill-of-Material, with ultra-low dynamic power.

The audio market for wireless Bluetooth headsets is growing rapidly. Audio devices using Bluetooth (BT) connectivity are more ubiquitous than ever. People have gotten used to wireless audio systems, and the mobile phone industry is pushing towards a world without audio connectors and cables. The latest trend in wireless headsets and speakers is True Wireless Stereo systems (TWS), consisting of two independent units that are each charged in their own charging case.
Using pulsed latches instead of flip-flops is a solution that has been thoroughly studied for its advantages in speed, density, and power consumption reduction [1] [2]. Even so, this solution has not been widely adopted by standard cell library providers because of the difficulties related to timing verifications: pulse width integrity and hold time closure. There is also a lack of EDA tools natively supporting this feature. Dolphin Integration delivers standard cell libraries based on pulsed latches (SESAME uHD libraries) that can be used in standard design flows and fully compatible with the most common EDA tools.
