Abstract
This paper improves a structure of bandgap reference independent to supply voltage and temperature, which can operate in the voltage range from 1.6 V to 5V successfully. The bandgap reference circuit generates a voltage of 0.94V as reference voltage, and it is fabricated in a 0.18μm BCD CMOS technology. The supply voltage is 5V and temperature coefficient achieve 10ppm/°C in the wide temperature range of -40°C to 100°C. The power supply rejection is 61.44dB at 12 kHz and the noise is 3.12pV2 /Hz. It occupies 146μm × 149μm and can be used for time to amplitude converter.
