Abstract-This paper presents a successful approach to increase the electromagnetic interference (EMI) immunity of CMOS bandgap reference circuits. Layout techniques along with some changes in the reference schematics lead to a robust electromagnetic immunity, preserving good overall performances. Measurement results confirm the low susceptibility of the proposed circuits. They exhibit only a few millivolts shift, for interfering signals of 1 Vpp in the frequency range of 1 MHz to 4 GHz, compared to the classi…
