Abstract

The invention provides a special three-level drive circuit for a CCD. The special three-level drive circuit for the CCD solves the problem that an existing three-level signal drive design scheme of a CCD image sensor is complex. The drive circuit comprises a first driver, a second driver and a triode. Both the first driver and the second driver comprise VDD ends, GND ends, signal input ends and signal output ends. The drive circuit is provided with two input ends and one output end. The two input ends of the drive circuit are the first input end and the second input end respectively. The first input end is connected with the signal input end of the first driver, and the second input end is connected with the base electrode of the triode. The signal output end of the second driver serves as the output end of the drive circuit. The special three-level drive circuit for the CCD can generate CCD sensor three-level signals of which the amplitude is stable.

Description

technical field [0001] The invention is used to generate a frame transfer signal of a CCD image sensor, relates to a design of a three-level driving circuit based on a CCD image sensor, and in particular relates to a special three-level driving circuit for a CCD. Background technique [0002] Some CCD image sensors require frame transfer signals such as figure 1 As shown, but there is no dedicated driver chip for generating three-level signals on the market, which needs to be designed by the user. At present, engineers who design driving circuits for three-level signals have designed many excellent schemes, but these design schemes are relatively complicated, so a simple three-level driving circuit design scheme is needed. Contents of the invention [0003] The invention provides a special three-level driving circuit for CCD, which can generate a three-level signal of a CCD sensor with stable amplitude, so as to solve the problem that the existing three-level signal drivi...
