Abstract
A double translation voltage level shifter is provided that includes a first translator comprising thin-gate devices and a second translator comprising thick-gate devices. The first translator is operable to receive an internal power supply voltage associated with an internal voltage domain, to receive a transitional power supply voltage associated with a transitional voltage domain, and to receive internal data. The internal data comprises data in the internal voltage domain. The first translator is also operable to generate transitional data based on the internal data, the internal power supply voltage, and the transitional power supply voltage. The transitional data comprises data in the transitional voltage domain. The second translator is operable to receive an external power supply voltage associated with an external voltage domain. The second translator is also operable to generate external data based on the transitional data and the external power supply voltage. The external data comprises data in the external voltage domain.
