In this paper, a bandgap reference (BGR) circuit that combines the capacitively biased diode (CBD) structure and the proportional-to-absolute-temperature (PTAT) voltage-embedded amplifier has been proposed. In order to enhance compatibility with digital domain supply voltage and achieve low power consumption, the supply voltage of the circuit is set at , benefiting from the fact that both the CBD structure and the PTAT-embedded amplifier can operate at sub-1 V supply voltages.
