Claim 4:
5. The mixed signal control circuit for eliminating the degenerate metastable state of the bandgap reference circuit according to claim 1, wherein: the degenerate state elimination circuit includes the non-volatile memory cell, the digital-to-analog conversion module and the delay switch unit,
after the non-volatile memory cell reads the binary data stored therein, the data is inputted to the digital-to-analog conversion module, and the digital-to-analog conversion module converts the digital input signal into an analog signal and inputs the analog signal to the delay switch unit, and
the delay switch unit is formed by a delay generation circuit, an inverter and a transmission gate circuit, wherein two control gates of the transmission gate circuit are controlled by an output signal and an inverted output signal of the delay generation circuit, respectively, and a delay signal input terminal of the delay switch unit is connected to an output identification signal output terminal of the digital-to-analog conversion module.
