Abstract
A temperature sensor includes a signal delaying apparatus, a comparison apparatus, a multiplier and a counting apparatus. The signal delaying apparatus is configured to receive a step signal, perform a phase delay operation on the received step signal according to a temperature degree, and thereby forming a first output signal. The comparison apparatus is configured to receive the first output signal and the step signal, and accordingly output a second output signal. The multiplier is configured to receive the second output signal and a clock signal, and accordingly output a third output signal. The counting apparatus is configured to receive the third output signal, count the number of pulses of the third output signal, and generate a digital code accordingly.
