Patent number: 12209919Abstract: A method for determining temperature of a chip, includes generating a first voltage and a second voltage using a pair of bipolar-junction transistors, and generating a third voltage using another bipolar-junction transistor. When a most recent bit of a bitstream is a logic-zero, the difference between the first and second voltages is sampled using a switched-capacitor input-sampling circuit, and a difference between the first and second voltages is integrated, to produce a proportional-to-absolute-temperature voltage. The proportional-to-absolute-temperature voltage is quantized to produce a next bit of the bitstream. When the most recent bit of the bitstream is a logic-one, the third voltage is sampled using the switched-capacitor input-sampling circuit, and the third voltage is integrated, to produce a complementary-to-absolute-temperature voltage.
