Abstract:
A first biasing potential is sent to a first input end of a first temperature coefficient of resistance (TCR) sensor having a first ground end coupled to a ground potential. A second biasing potential is sent to a second input end of a second TCR sensor having a second ground end coupled to the ground potential. The first and the second biasing potentials are changed to operate in a plurality of modes.
