Dolphin Design has combined two of their SPEED platforms into an audio development platform on the TSMC 22nm ultra-low leakage (22ULL) process, a foundry solution for IoT and wearable devices applications, enabling improved levels of integration to embed more functionalities on a single die.
This combo looks to reduce Bill-of-Material costs by embedding all power management functions and thus remove the external PMIC, and ensure great audio subsystem performances for the best human-voice control of the final device.
With Dolphin Design’s core expertise in analogue design, the SPIDER and BAT platforms fit together perfectly for an easy and fast implementation:
- Sleep mode: power supply optimisation of the VAD through a dedicated uLP DCDC
- Active mode: audio power supply rejection rate complies with DCDC characteristics
- Consistent views and deliverables
The audio-oriented design platform contains:
SPIDER – Power management platform
- 2 ultra-low quiescent with high efficiency DCDCs
- A nano power LDO
- POR BOR
BAT – Analogue & digital audio platform
- 6 input channel ADC with phase alignment to guarantee software algorithm performances
- 2 output channel digital DAC to reduce silicon area and integration costs
- Voice Activity Detection for ultra-low power consumption in always listening modes
Fabless companies can ask Dolphin Design to combine SPEED platforms to address their specific SoC requirements to save time, energy, and ensure their Time-to-Market while focusing on their core competencies.
