Abstract
A system for analyte measurement includes a programmable gain amplifier including a first input terminal operatively coupling to the output of a sensor for sensing an analyte, a second input terminal operatively coupling to a voltage source, and an output terminal for providing an output based on a difference between inputs on the first input terminal and the second input terminal A controller is operatively coupled to the programmable gain amplifier for configuring the operation range of the programmable gain amplifier and/or selecting the output of the programmable gain amplifier for analyte measurement. The method includes monitoring an output from a programmable gain amplifier operatively coupling to a sensor for sensing an analyte, and controlling the operation range of the programmable gain amplifier, and/or selecting the output of the programmable gain amplifier for analyte measurement.
