A bandgap reference circuit having a low sensitivity to temperature and supplied voltage installs a compensation circuit on a bandgap reference circuit to substitute a prior art that uses a resistor to match the circuit startup purpose and solve the problem of startup error caused by the manufacturing error. The bandgap reference circuit includes a first amplifier, a second amplifier, and a reference circuit having a plurality of transistors and a plurality of bipolar junction transistors, and the bandgap reference circuit is electrically connected to a same supplied power of which the reference circuit is electrically connected and also includes a plurality of transistors and a compensation circuit of the second amplifier, so as to output a stable startup voltage which has a low sensitivity to the change of temperature and the change of supplied voltage.
