OUTPUT CIRCUIT ADAPTED FOR INTEGRATED CIRCUIT AND ASSOCIATED CONTROL METHOD |
| 摘要 |
An output circuit adapted for an integrated circuit is provided. The output circuit includes a driver, a pre-driver and a buffer circuit. The driver is electrically connected to two output nodes outside the integrated circuit to output signals. The pre-driver controls the driver, and includes a load and an input transistor connected in series. Between the load and the input transistor is a connection node for controlling the driver. The buffer circuit controls the load and the input transistor according to an internal signal. Before turning off the input transistor, the buffer circuit pre charges the connection node through the load. |
