  • Output stage circuit and related control method
    Patent number: 11025253
    Abstract: An output stage circuit includes a first operational amplifier, a second operational amplifier, a switch circuit, a clamp circuit and at least one pull-low transistor. The first operational amplifier is operated in a first voltage domain. The second operational amplifier is operated in a second voltage domain. The switch circuit is coupled to the first operational amplifier and the second operational amplifier. The clamp circuit is coupled between the switch circuit and a plurality of output terminals of the output stage circuit. The at least one pull-low transistor is coupled to the switch circuit.
    Type: Grant
