Description
Summary:In this paper we show a stable glucose monitoring system for vertically aligned carbon nanofiber based biosensors. The system is comprised of a modified grounded working electrode potentiostat using a common gate transimpedance amplifier and a current starved voltage controlled oscillator. The system provides a low power solution for portable applications and facilitates wireless data transfer. The system is implemented in a commercially available 0.18μm 6 metal 1 poly standard CMOS process. The potentiostat consumes 72.4μW of power from a 1.8V supply, and the system occupies 0.0457mm 2 of chip area.
