Abstract
Systems, methods and devices relate to remote temperature sensing responsive to fractional currents used to bias a remote temperature diode. Fractional currents may be selected to simplify at least some temperature calculations performed using digital logic. Values of at least two voltage changes may be determined at least partially based on values of voltages generated across a pair of nodes at least partially responsive to excitation currents. Such pair of nodes associated with sensing paths coupled with a remote diode. A value of temperature may be determined at least partially based on the values of at least two voltage changes and a stored value of a fractional mirror ratio. The fractional mirror ratio represents a relationship between current magnitudes of excitation currents.
