Abstract

In this work, recent advances in the development of a micropower SoC platform aimed at implantable medical devices are presented. A RISC-V CPU core was designed, fabricated in a 180nm CMOS-HV technology, and measured. Also, a 25mA(max), 8 bits programmable integrated current source is included within the SoC to directly drive tissue stimuli. The proposed circuit includes a 6-bits trimming mechanism to balance sink/source outputs to a precision below 1%. The current source operates up to 18V supply. SoC measurements are presented, showing a close agreement with previously simulated results in both analog and digital circuits. The RISC-V core properly operated up to 30MHz with a current consumption of ∼50μA/MHz@ 1.8V VDD.
