Abstract (en)
A proportional-to-absolute-temperature current generating device includes a differential difference amplifier (DDA) that outputs a comparison signal based on a reference voltage, a first voltage, and a second voltage, a current source that generates a first current and a second current based on the comparison signal, a proportional-to-absolute-temperature voltage (VPTAT) generating unit that generates the first voltage based on the first current, and a complementary-to-absolute-temperature voltage (VCTAT) generating unit that generates the second voltage based on the second current. Each of the first current and the second current is a proportional-to-absolute-temperature current that increases in proportion to a temperature of the proportional-to-absolute-temperature current generating device.
