Abstract
A control buffer circuit includes a voltage detection circuit configured to detect whether a received voltage is a negative voltage or a ground voltage and provide a voltage detection signal based on a result of the detecting, and a buffer circuit configured to provide a switching signal based on the voltage detection signal, wherein the switching signal comprises a positive voltage as a switching-on level voltage and includes one or more of the ground voltage and the negative voltage as a switching-off level voltage.
