A CMOS system-on-chip for physiological parameters acquisition, processing and monitoring

摘要

A system-on-chip allowing dynamic measurement and processing of the most important human physiological parameters has been presented. The BioChip consists of analog front-ends, analog to digital converters and a two core 32-bit microcontroller Azurite. The two core architecture allows to control the signals' acquisition, data processing and communication with the peripherals simultaneously. The microcontroller was equipped with many interfaces: 8×UART, 2×SPI, I2C and 24 GPIOs. The clock frequency of the microprocessor is configurable from 32 kHz up to 120 MHz. The BioChip comes in front of the growing demand for portable health monitoring. It will allow for easy integration with a new generation of devices, such as smartphones, and also it will allow adding new functionalities in the area of telemedicine. The BioChip was designed in UMC CMOS 130 nm technology and the chip area is 25 mm.
