Abstract
A thermometer circuit configured to estimate a monitored temperature is disclosed. The circuit includes an adjustable resistor presenting a first resistance value that is temperature-independent and a second resistance value that is temperature-dependent, wherein a first current signal is conducted across the resistor when it presents the first resistance value and a second current signal is conducted across the resistor when it presents the second resistance value; a plurality of gated conductors coupled to the resistor; and a control circuit, coupled to the resistor and the plurality of gated conductors, and configured to selectively deactivate at least one of the plurality of gated conductors to compare the first and second current signals to estimate the monitored temperature.
