An EMI Susceptibility Improved, Wide Temperature Range Bandgap Voltage Reference
Original language description
This article presents a new electromagnetic compatibility improved bandgap voltage reference with a low-current consumption of only 3.2 μA. The reference is designed for automotive applications with an extended temperature range from −50 to 200 °C and a low electromagnetic interference (EMI) susceptibility. The designed reference comes from the well-known Brokaw bandgap topology utilizing only five bipolar junction transistors in a reference core with a collector current leakage compensation. We propose several novel EMI susceptibility improvements of the reference core with a new asymmetrical operational amplifier. Every improvement is discussed in detail and general recommendations, on how to decrease the bandgap EMI susceptibility, are presented. Simulation results are compared with measurements on a system on chip. Measurement results show dc voltage variation below 0.5% for 5 mW (7 dBm) supply EMI over the frequency range from 100 kHz to 1 GHz.
