  • Patent number: 10260957
    Abstract: A time domain integrated temperature sensor described by the present invention adopts a shaped clock signal to control the charging time of capacitors, so that the capacitors generate charging time delay signals related to the cycle of an input clock, and a pulse signal related to pulse width, temperature and the cycle of the input clock is generated through logical XOR (Exclusive OR) operation on a time delay signal generated when the capacitors are charged by one way of PTAT (Proportional To Absolute Temperature) current in an above control manner and a time delay signal generated when the capacitors are charged by one way of CTAT (Complementary To Absolute Temperature) current in the same manner; then, the same input clock signal is adopted for quantifying the pulse width of the pulse signal, the relevance of the obtained quantization result and the cycle of the input clock is completely offset, namely, an output value of the temperature sensor is unrelated to the input clock signal, thereby solving the pr
