Abstract
In certain aspects, a device comprises one or more IO inputs; a first receiver coupled to a first supply voltage and the one or more IO inputs, wherein the first receiver comprises thick oxide transistors; and a high-speed circuit comprising: an isolation block coupled to the one or more IO inputs, wherein the isolation block comprises thick oxide transistors; and a second receiver coupled to the isolation block and a second supply voltage, wherein the second receiver comprises thin oxide transistors.
Claims39
A device, comprising:
- one or more IO inputs;
- a first receiver coupled to a first supply voltage and the one or more IO inputs, wherein the first receiver comprises thick oxide transistors;
- and
- a circuit comprising:
- an isolation block coupled to the one or more IO inputs, wherein the isolation block comprises thick oxide transistors;
- and
- a second receiver coupled to the isolation block and a second supply voltage, wherein the second receiver comprises thin oxide transistors, wherein the first receiver is configured to be disabled when the isolation block is configured to couple the one or more IO inputs to the second receiver, and wherein the first receiver is configured to be enabled when the isolation block is configured to decouple the one or more IO inputs from the second receive.

A method, comprising:
- receiving a signal through one or more IO inputs;
- enabling a first receiver if the signal is a first type signal or coupling the signal to a second receiver through an isolation block coupled to the one or more IO inputs if the signal is a second type signal, wherein the first receiver couples to a first supply voltage and comprises of thick oxide transistors, the second receiver couples to a second supply voltage and comprises of thin oxide transistors, and the isolation block comprises thick oxide transistors;
- and
- disabling the first receiver if the signal is the second type signal and decoupling signal from the second receiver if the signal is the first type signal.
