VOLTAGE AND CURRENT REFERENCE GENERATOR |
摘要 |
A voltage and current reference generator includes: a temperature-insensitive voltage source for providing a first current with a positive temperature coefficient and a reference voltage with a substantially zero temperature coefficient according to a junction voltage difference with a negative temperature coefficient; a mirror unit for mirroring the first current to obtain a second current with the positive temperature coefficient and for generating a junction voltage with the negative temperature coefficient according to the second current; a voltage-to-current conversion unit for converting the junction voltage into a third current with the negative temperature coefficient; and a current integration unit for obtaining a fourth current and a fifth current, and integrating the fourth current and the fifth current into a reference current having a substantially zero temperature coefficient.
