Abstract
A device for grounding pop-click noise may include an output block configured to generate an output signal at an output node. A switch circuit coupled to the output node may be configured to be operable to couple the output node to a ground potential. The switch circuit may include a first and a second transistor. A drain, a source, and a gate node of the first transistor may be coupled to the output node, a drain node of the second transistor, and a first control signal, respectively. A drain, a source, and a gate node of the second transistor may be coupled to a source node of the first transistor, the ground potential, and a second control signal, respectively. The first and the second control signals may operate the switch circuit to couple the output node to the ground potential during a pre-determined period associated with the pop-click noise.
