Analog Designers Face Low Power Challenges

Can mixed signal designs achieve the low power needed by today’s tightly integrated SoCs and embedded IoT communication systems?

System level power budgets are affected by SoC integration. Setting aside the digital scaling benefits of smaller geometric nodes, leading edge SoCs achieve higher performance and tighter integration with decreased voltage levels at a cost. If power is assumed to be constant, then that cost is the increased current flow (P=VI) delivered to an ever larger number of processor cores. That’s why SoC power delivery and distribution remain a major challenge for chip architects, designers and verification engineers.

As with digital engineers, analog and mixed signal power designers must consider ways to lower power consumption early in the design phase. Beyond that consideration, there are several common ways to reduce the analog mixed signal portion of a power budget. These ways include low-power transmitter architectures; analog signal processing in low-voltage domains; and sleep mode power reduction. (ARM’s Diya Soubra takes about mixed signal sleep modes in, “Digital Designers Grapple with Analog Mixed Signal Designs.”)

Experts Share Unique Challenges in Wearable Designs

Wearable devices will add a new twist to traditional embedded designs according to experts from ARM, Freescale, HillCrest Labs, STMicr, Imec and Koinix.

Wearable technology design presents challenges different from other embedded markets. To understand these challenges, “System Design Engineering” talked with James Bruce, Director Mobile Solutions forARM; Mike Stanley, Systems Engineer at Freescale; Daniel Chaitow, Marketing Communications Manager at Hillcrest Labs; Jay Esfandyari, Director of Global Product Marketing at STMicroelectronics; Siebren Schaafsma, Team Leader at Holst Centre and Imec, and; Thea Rejman, Financial Analyst at Kionix, Inc. What follows is a portion of that conversation. – JB
