Minimizing the PCB footprint and the BoM cost implies embedding the Power Regulation Network (PRNet) in the SoC.
Meanwhile, minimizing drastically the SoC power consumption involves implementing several modes of activity to turn on and off different functions of the SoC, which generates noise on the supply lines during mode switching.
Dolphin Integration is pioneering the fabric of PRNet.
Discover the solutions to achieve the lowest power consumption with the smallest silicon area thanks to the mastery of noise propagated on supply lines:
- A Reduced Power Kit Library (RPKL) compliant with the DELTA Standard – from 180 nm down to 28 nm – which encompasses various kinds of voltage regulators to meet most SoC requirements:
- eSR-Niagara, a switching regulator providing the best compromise between power savings (down to a mere 5 % of energy waste) and small silicon area.
- qLR-Aubrey, a linear regulator with an ultra-low quiescent current of 150 nA including the voltage reference, to supply the Always-on Power Domain.
- Retention Alternating Regulator (RAR), a unique voltage regulator, first of its kind, which ensures the lowest waste of energy in each power mode – both active and retention – of a power island.
- nLR-Charny, an ultra low-noise linear regulator to supply sensitive analog converters or RF loads.
- iLR-Victoria, a linear regulator to supply logic loads or conventional analog loads. It combines small area with fast load transient and fast wake-up time….
- DELTA Integration Rules, a set of guidelines ensuring that all constraints are addressed at PRNet level.
Pushing SoC optimizations near the limits and risking to improperly size the PRNet is daunting! Dolphin Integration’s voltage regulators, benefiting from the DELTA Integration Rules, allow proceeding with a set of unavoidable verifications when dealing with embedded PRNet, and enable SoC designers to determine necessary but not oversized margins.
To easily proceed with the needed verifications, Dolphin Integration enables simulating early in the design flows thanks to EDA Solutions.
