摘要
Existing proportional to absolute temperature (PTAT)/ complementary-to-absolute-temperature (CTAT) reference voltage circuit requires a large components count and foot print, precise device matching for accuracy and unsatisfactory sensitivity error or variation to temperature and humidity. The present invention relates to a novel approach for such reference voltage circuit based on a self- biased complementary pair of n-type and p-type current field-effect transistors, which provides rail PTAT, rail CTAT and analog reference voltages.
