In this work an integrated low supply voltage, low-power 1.03V voltage reference for implantable medical devices is presented. The circuit was designed, simulated and fabricated in a 0.6 μm technology. Simulated and measured results show that output voltage varies less than 3 mV while varying supply voltages from 1.7V to 5V, and has a standard deviation of 13 mV between different measured chips. To reduce the power consumption the output is buffered and the bandgap circuit is periodically turned on and off, resulting in a total current consumption of less than 200 nA, which fits regular requirements of medical devices.
