Abstract
A clamp circuit including a power supply node and a ground node. A first node is selectively coupled to the power supply node during a first state and selectively coupled to the ground node in a second state. A second node provides a first clamp voltage in the first state and a second clamp voltage in the second state. The first and second nodes are coupled by, for example, a plurality of series-coupled bipolar junction transistors having a common collector coupled to the first node.
