Abstract
A method and circuit for determining a working temperature of a device, the method comprising: providing a first signal to a device having a temperature-sensitive characteristic; performing a function on the first signal by the device; demodulating a second signal output by the device to obtain a third signal thus generating a signal having reduced 1/f noise component; and based upon the first signal and the second signal, determining a working temperature of the device.
