Abstract
A semiconductor apparatus includes an input selection circuit that selects one of a first input signal and a second input signal in response to a control signal, and outputs the selected input signal as a selection signal, wherein swing levels of the first input signal and the second input signal are different one another. The semiconductor apparatus also includes a conversion circuit that generates an output signal, in response to the selection signal, which swings to a level substantially identical to a level of the second input signal.
Claims16
A semiconductor apparatus comprising:
- an input selection circuit configured to select one of a first input signal and a second input signal in response to a control signal and configured to output the selected input signal as a selection signal, wherein swing levels of the first input signal and the second input signal are different from one another;
- and
- a conversion circuit configured to generate an output signal, in response to the selection signal, wherein the output signal swings to a level substantially identical to a level of the second input signal,
- wherein the input selection circuit comprises:
- a first input circuit configured to transfer the first input signal to an output circuit;
- a second input circuit configured to transfer the second input signal to the output circuit based on the control signal;
- and
- the output circuit configured to perform at least one of an inverting operation and a resistive feedback inverting operation on the first and second input signals, received from the first and second input circuits, based on the control signal and output a result of the operation as the selection signal.

A semiconductor apparatus comprising:
- a first input circuit comprising a capacitor that receives a first input signal at a current mode logic (CML) level and transfers the first input signal to an output circuit;
- a second input circuit configured to, based on a control signal, transfer a second input signal at a complementary metal-oxide semiconductor (CMOS) level to the output circuit or substantially prevent the transfer of the second input signal to the output circuit;
- and
- the output circuit configured to perform at least one of an inverting operation and a resistive feedback inverting operation on output of the first and second input circuits based on the control signal,
- wherein the output circuit performs the resistive feedback inverting operation on the output of the first input circuit based on the control signal when the output of the first input circuit is transferred to the output circuit, and
- wherein the output circuit performs the inverting operation on the output of the second input circuit based on the control signal when the output of the second input circuit is transferred to the output circuit.
