Abstract
A battery powered system includes a voltage level shifter, an anti-aliasing filter, a pair of switches, a unity gain differential buffer, a second pair of switches, and an analog-to-digital converter. The first pair of switches couple the differential output port of the voltage level shifter to the differential input port of the anti-aliasing filter. The second pair of switches couple the differential output port of the anti-aliasing filter to the differential input port of the unity gain differential buffer. The analog-to-digital converter is coupled to the differential output port of the unity gain differential buffer.
