LOW VOLTAGE SWING BUFFER

摘要

An apparatus includes a first circuit of a first type that couples an output node to a first power supply node in response to a first value of a control signal. The apparatus includes a second circuit of a second type to couple the output node to the first power supply node in response to a first value of a first signal having a first voltage swing. The apparatus includes a third circuit of the second type to couple the output node to a second power supply node in response to a second value of the first signal. The apparatus includes a control circuit that generates the control signal based on the first signal and an output signal on the output node. The first, second, and third circuits generate an output signal on the output node. The output signal has a second voltage swing less than the first voltage swing.
