CEA-Leti and STMicroelectronics presented an order-of-magnitude-faster FD-SOI Ultra-Wide-Voltage Range (UWVR) DSP at ISSCC ’14. The device was produced by ST in 28nm UTBB FD-SOI. It allows body-bias-voltage scaling from 0V to +2V, decreases minimum circuit operating voltage and supports clock-frequency operation of 460MHz at 400mV.
“This demonstration DSP shows that FD-SOI is blazing the trail for better portable and battery-powered products, using more efficient semiconductor chips, all the way down to the 10nm node,” said Philippe Magarshack, Executive Vice President, Design Enablement Services, STMicroelectronics.
The Leti/ST paper, entitled, “A 460MHz at 397mV, 2.6GHz at 1.3V, 32b VLIW DSP, Embedding Fmax Tracking,” was presented during Session 27, “Energy-Efficient Digital Circuits”. A demonstration kit was shown to ISSCC attendees. ISSCC – the International Solid-State Circuits Conference – is the flagship conference of the Solid-State Circuits Society. It is widely considered the premier forum for presenting advances in solid-state circuits and systems-on-a-chip.
