Abstract
A temperature sensor comprises a first oscillator to provide a first oscillation signal having a frequency that increases with increasing temperature and a second oscillator to provide a second oscillation signal having a frequency that decreases with increasing temperature. A time domain sigma-delta modulator is coupled to the first and the second oscillator to receive one of the first oscillation signal and the second oscillation signal to generate an output signal including a bitstream.
