Abstract
Battery life specifications drive the power con-
sumption requirements of integrated circuits in implantable,
wearable, and portable medical devices. In this paper, we present
an embedded processor platform chip using an ARM Cortex-M3
suitable for mapping medical applications requiring microwatt
power consumption. Ultra-low-power operation is achieved via
0.5–1.0 V operation, a 28 fW/bit fully differential subthreshold
6T SRAM, a 90%-efficient DC-DC converter, and a 100-nJ
fast Fourier transform (
