Claim:
1. A bandgap reference circuit, comprising: a first set of two or more bipolar junction transistors (BJTs) configured to electrically connect in a parallel arrangement, wherein the first set of BJTs is configured to produce a first proportional to absolute temperature (PTAT) signal; and a second set of two or more BJTs configured to electrically connect in a parallel arrangement, wherein the second set of BJTs is configured to produce a second PTAT signal, wherein the first set and the second set of BJTS are collectively arranged in a centroid type pattern, and a number of BJTs in the second set is defined by Q=(n+E)×(m+E)−n×m, where Q is the number of BJTs in the second set, n is a number of rows of BJTs in the first set, m is a number of columns of BJTs in the first set, and E is an even integer.
