SIGNAL CONVERSION

摘要

A circuit may include an input terminal configured to receive an input signal with a first voltage swing and an output terminal. The circuit may also include a first transistor, a second transistor, a third transistor, and a control circuit. The control circuit may be coupled to the input terminal, a gate terminal of the first transistor, and a gate terminal of the second transistor. The control circuit may be configured to adjust voltages provided to the gate terminals based on the input signal such that the first transistor conducts in response to the input signal being at a first logical level and the second transistor conducts in response to the input signal being at a second logical level to generate an output signal output on the output terminal. The second voltage swing of the output signal may be different from the first voltage swing of the input signal.
