Fabless semiconductorFrench silicon IP component manufacturer Dolphin Integration has released a new product for fabless and system on chip (SoC) integrators with the aim of targeting smart grid services including utility billing meters. 

The Metro-PM-Jade-mono.05 product, featuring a measurement subsystem for single-phase power metering ICs, is available in main technological processes at 130 nm.

Users of Metro-PM-Jade-mono.05 benefit from a high-resolution mixed-signal front-end (sensAFE-20x32-PM-mono.05-LB) and a dense power and energy computation engine (PCE-PM.01), the company said in a statement this week.

The SoC-enabling product also embeds a low drift voltage reference and a low noise voltage regulator ensuring the reduction of the bill of material and the safest integration, due to lower supply noise constraints.

Achieves range beyond 1/5,000

The Grenoble-based company has made the public the results of its silicon measurement report in TSMC 130 BCD process for its silicon qualifier containing the analog front-end, which the company says demonstrates its ability to contribute to power metering applications.

The analog front-end has been tested associated with a current transformer sensor and features a SNR up to 106.0 dB on the I-channel and 102.8 dB on the V-channel.

Its performances enable power-metering subsystems to achieve class 0.1 performances with a range beyond 1/5,000 at the system level.

Founded in 1985, Dolphin Integration has manufactured virtual components using a virtual fab process where silicon qualifiers serve to validate the equivalence between simulations and measurements.
