  • Patent number: 8519771
    Abstract: Methods and apparatus for receiving high voltage signals using a receiver designed in a low supply voltage technology are disclosed. One embodiment of an integrated circuit includes a single ended driver including an n-type metal-oxide-semiconductor (NMOS) transistor and a p-type metal-oxide-semiconductor (PMOS) transistor. An input pass gate is coupled to the single ended driver, and is configured as a PMOS pass gate coupled in parallel with the NMOS transistor in the single ended driver. In a low voltage mode, the NMOS transistor and the PMOS pass gate form a first pass gate for transmitting the input signal to the receiver. In a high voltage mode, the PMOS pass gate is disabled, and the NMOS transistor and PMOS transistor form a second pass gate for transmitting the input signal to the receiver.
