A High Performance Bandgap Voltage Reference with Degeneracy Optimization
Jun Zhang · 2008
A high-precision and low-temperature voltage reference source was proposed based on classical topology of voltage reference,and theory of finding and canceling degeneration for designing start-up circuit was presented.The circuit was implemented in XFAB's 0.6 μm CMOS process.Test results showed that the reference source had a voltage precision of 1.202 ± 0.2 mV at 2.45 V to 16 V,and a temperature coefficient between 7.6 ppm/ ℃ and 9 ppm/ ℃ in the temperature range from-10 ℃ to 80 ℃,with a max power of 0.32 mW.
