Description

This continuous glucose monitor (CGM) reference design provides a comprehensive evaluation platform for TI's latest resources in low-power and continuous monitoring of glucose for diabetes care. The reference design utilizes an analog front-end (AFE) for low-power and accurate electrochemical sensing with up to two channels. The TMP63 or TMP118 can monitor body temperature to increase accuracy in glucose sensing. Electrochemical sensor readings are processed by the low-power CC2340R5 Bluetooth® Low Energy (LE) microcontroller and are transmitted to a smartphone for real-time display and data collection. Flexible selection of low-I_Q voltage converters enables support for battery input from silver-oxide (1.5V) and lithium batteries (3.0V), while maintaining a compact design of less than 20mm in diameter.
