A bandgap reference voltage cell that produces a first-order and a second-order temperature-compensated reference voltage output includes four bipolar transistors. At least one of the four transistors is biased with a current having a different temperature coefficient than that of a current which biases at least the second of the four transistors. The first and second order temperature compensation to the reference voltage is realized within the bandgap cell itself.
