Abstract:
A reference voltage source of integrated circuit is featured as applying nonlinear correction technique to counterbalance logarithmic term in temperature coefficient of output current to make outputted voltage source have very high temperature stabilization, applying level displacement circuit to replace traditional voltage dividing resistance for decreasing temperature influence caused by area and resistance, varying value of parallel internal resistance at output end for realizing large variation of voltage value with temperature stabilization, setting startup and offset circuit to let circuit start up correctly.
