Abstract
Closed loop voltage clamp circuits and related methods are disclosed that can be used in a variety of applications including USB (Universal Serial Bus) Type-C connections. The voltage clamp embodiments operate to clamp a voltage on a circuit node. A driver stage is coupled between the circuit node and ground. A pass circuit stage is coupled between the circuit node and ground, has a control node coupled to the output of the driver stage, and is configured to control the voltage on the circuit node. The feedback amplifier stage is coupled between the circuit node and ground and has an output node coupled to the input node of the driver stage. The driver stage, the pass circuit stage, and the feedback amplifier stage operate as a closed loop circuit without reference voltage and supply voltage connections.
