Abstract
We report a system-on-chip (SoC) realised in 130nm CMOS for implantable telemetry systems and mobile health applications featuring 6 neural stimulation channels and acquisition circuits for 9× electrode-based recordings (ExG), 4×/32× photo-plethysmography (PPG), bio-impedance, and temperature. The SoC includes a low-power quad-core processor (34μW/MHz) with sophisticated power and clock management - enabling power-gating, load-aware voltage scaling, and selective clock-gating. The latter is demonstrated on the example of preliminary work on an implantable telemetry device for vital signs monitoring.
