Abstract
An input buffer is provided and includes a current mirror circuit and a first amplifier. The current mirror includes first to second transistors. The first transistor is configured to couple a current source at a first node. The second transistor is coupled with the first transistor and is configured to output, according to a first current flowing through the first transistor, a second current at a second node. The first amplifier is coupled with the current mirror circuit at the second node, and includes a first transistor pair. A first breakdown voltage of the first transistor pair is smaller than a second breakdown voltage of the second transistor. The first transistor pair is configured to generate, in response to the second current and first to second input voltages, first to second voltages.
