Bandgap References

Analog Alchemy offers a broad range of bandgap voltage reference (BGR) IPs, which are characterized for various CMOS technologies. There are different BGR architectures available, which are optimized for different performance levels and power supply voltages, ranging from 0.9V to 3.3V. All BGR architectures comprise a robust start-up circuit and a bias current generator with multiple current outputs. The BGRs are specified from junction temperature of -40°C to +125°. The BGRs consumes little power while realizing excellent DC and PSRR characteristics.

BGR Concept for Power Supply voltages VDD < 1.2V

Robust Startup required(!):

  • The bidiodes are biased at start by a startup current (Istart)
  • Istart is generated from a VBE, to ensure a temperature independent startup
  • OTA is continuously biased by independent circuit
  • Adaptive persistence of startup current
  • startup is not dependent on any loop bandwidth
