Field: Control (Instruments)
Classification: CPC G  H | IPC G  H

Claim 3:
4. The mixed signal control circuit for eliminating the degenerate metastable state of the bandgap reference circuit according to claim 1, wherein: an output terminal of the digital-to-analog conversion module is connected to an negative input terminal of the self-biased bandgap reference temperature compensation loop circuit through the delay switch unit, and is configured to perform a voltage clamping operation on the negative input terminal through a preset analog voltage value during the start-up process, wherein relying on output driving capability of the digital-to-analog conversion module, the voltage of the negative input terminal is forced to be stabilized at the preset analog voltage value, thereby eliminating the possibility of the bandgap reference circuit entering the degenerate metastable state.
