Abstract
A simplified electronics approach to allow cost, size, and power consumption to be reduced while maintaining state of the art accuracy and reliability, key features for wireless medical devices/systems. Extreme accuracy is achieved by innovative noise shaping and filtering introduced to the electrochemical sensor, before sampling by the analog to digital converter. Introduction of the noise to the electrochemical sensor provides very low power biasing which is necessary to achieve overall reliable and very accurate bias for the electrochemical reaction cell.
