UK mobile phone power supply developer Nujira raises $20m


Nujira, a UK-based startup that specialises in mobile handset power supply chips, has raised $20m  to develop its chip technology.

The fundraising round was led by existing investors Amadeus Capital Partners, Climate Change Capital, Environmental Technologies Fund, SAM Private Equity and NES Partners, as well as new investors GAM and Investec.

Nujira uses a power saving technology called envelope tracking to optimise efficiency in smartphones and tablets.

Over recent years envelope tracking has become increasingly popular among smartphone manufacturers as applications and hardware become more demanding. The Nexus 5, Galaxy Note 3 and One M8 all include the technology in some form.

Nujira said it plans to open a new design centre in Santa Clara, California. It said the new design centre will focus on the development of next generation envelope tracking chips.
