onsemi CEM102 Analog Front End (AFE)

Designed for accurate continuous glucose monitoring (CGM)

onsemi features their CEM102 analog front end (AFE) specifically developed for continuous glucose monitoring (CGM) and other applications using amperometric measurements where sensing very low currents is required.

Featuring its small form factor and low power consumption, the CEM102 enables further miniaturization and increase of battery life for many end applications. This AFE is designed to be used together with onsemi’s RSL15 (Secure Bluetooth® 5.2 wireless MCU), bringing several additional system-level benefits such as operating at optimized system power consumption and supply voltage. This includes operating the system at a wide 1.3 to 3.6 V supply voltage range, typically using a single 1.5 V silver oxide battery or a 3 V coin cell.

Features

  • Completely 2 channel solutions for electrochemical measurement (CEM102+RSL15)
  • Support 1,2,3 or 4 electrodes
  • Extremely low system current consumption
  • High resolution ADC, several DACs for bias setting and factory trimmed system
  • Detection for abnormal sensor conditions and Host processor wake up
  • Small footprint area

Applications & End Products

  • Electrochemical measurement systems
  • Continuous Glucose Monitor
  • IoT sensor devices
  • Wearables

 

Evaluation Board
CEM102-EVB

There is also a CEM102 evaluation board that in addition to CEM102 includes RSL15 together with sample code to set up and perform measurements with CEM102. This facilitates a jump start of system and FW development.
