ABSTRACT:
A switch circuit is disclosed. The switch circuit may include one or more arrangements of transistors coupled in a cascode configuration. The transistors used to implement the switch circuit may be configured for operation within a first range of voltages. The application in which the switch circuit may be implemented may require conveying signals within a second range of voltages that is greater than the first range of voltages. Thus, the switch circuit may include one or more additional transistors to ensure that a voltage drop between any two terminals of the transistors used in the switch circuit is within the first range of voltages.
