Abstract:
A bandgap reference circuit including two sets of bipolar junction transistors (BJTs). A first set of two or more BJTs configured to electrically connect in a parallel arrangement. The first set of BJTs is configured to produce a first proportional to absolute temperature (PTAT) signal. A second set of two or more BJTs configured to electrically connect in a parallel arrangement. The second set of BJTs is configured to produce a second PTAT signal. A circuitry configured to electrically connect to the first set of BJTs and the second set of BJTs. The circuitry is configured to combine the first PTAT signal and the second PTAT signal to produce a reference voltage.
