Abstract
A driving circuit includes: a primary driver configured to receive a first signal and generate a second signal based on the first signal, driving capability of the second signal being greater than that of the first signal; and an auxiliary driver connected to an output terminal of the primary driver and configured to receive the first signal and generate an auxiliary driving signal based on the first signal, the auxiliary driving signal being configured to shorten a rise time of the second signal.
Claims17
A driving circuit, comprising:
- a primary driver configured to receive a first signal and generate a second signal based on the first signal, driving capability of the second signal being greater than that of the first signal;
- and
- an auxiliary driver connected to an output terminal of the primary driver and configured to receive the first signal and control ON/OFF of a semiconductor device for generating an auxiliary driving signal based on the first signal, the auxiliary driving signal being configured to shorten a rise time of the second signal.
A driving circuit, comprising:
- a second pull-up transistor configured to generate an auxiliary driving signal and output the auxiliary driving signal to a primary driver, the auxiliary driving signal being configured to shorten a rise time of an output signal of the primary driver;
- a periodic clock generation component configured to generate a clock signal with a duty ratio of 50%;
- and
- an edge enhancement circuit connected to the periodic clock generation component and a control terminal of the second pull-up transistor, the edge enhancement circuit being configured to receive the clock signal and a first signal inputted externally and generate an edge enhancement signal based on the clock signal and the first signal, and the edge enhancement signal being configured to control ON/OFF of the second pull-up transistor.
