AbstractThe BioSoC is a highly integrated SoC that consists of analog front-ends, analog to digital converters and a 32-bit microcontroller - Adelite. The designed IC allows for dynamic acquisition and processing of the most important human physiological parameters. The provided analog interfaces to external electrodes and sensors allow measurement of electrocardiograms (ECG), electromyograms (EMG), skin temperature and resistance, and respiration rate (RR). After analog processing signals are sampled and digitized in analog-to-digital converters they can be further processed in a 32-bit microcontroller Adelite. The clock frequency of the microprocessor core is configurable from 32 kHz up to 16 MHz. The microcontroller is equipped with many digital interfaces and peripherals, such as 2×UART and 2×SPI with DMA channels, 16 GPIOs and 5 timers along with RTC. The BioSoC makes it possible to build highly integrated devices with rich functionalities in the area of telemedicine that respond to the growing demand for portable health monitoring. The BioSoC was designed and fabricated in UMC CMOS 130 nm technology process and occupies the area of 25mm2.
