Abstract

A pulse driver with variable level displacement and variable output amplitude belongs to the technical field of pulse electronic circuits, in particular relates to a topological structure of a driving circuit in the electronic circuit. The invention comprises the following steps: two basic electronic circuits are composed of two triodes and a resistance, wherein a first basic electronic circuit is designed as a paraphase follower and a first voltage reference point is led, and a second basic electronic circuit is connected as an emitter follower and a second voltage reference point is lead. The structure of the invention is that: the two basic circuits are connected and communicated with each other by diodes at a positive direction; the two voltage reference points are connected by the resistance. The pulse driver has the effective results that usual diodes, triodes and resistors employed in the circuit realize the reference level displacement between a driving circuit and a driven circuit, meanwhile, conveniently regulate pulse extent, and the large output power facilitates integration. The invention provides the pulse driver which can be easily mass-produced, with low cost and can be widely applied in every electronic field to market.

Description

technical field [0001] It belongs to the technical field of pulse electronic circuits, and specifically relates to the topological structure of driving circuits in electronic circuits. Background technique [0002] In some electronic pulse circuits, the reference potentials of the pulse driving circuit and the driven circuit are not equipotential, that is, there is a level shift. The usual solution is to use a photocoupler to deal with it. This method has the following disadvantages: 1. It is not easy to increase the driving power, 2. It is not easy to adjust the pulse output amplitude as required, and 3. It is not easy to integrate. Contents of the invention [0003] The invention provides a pulse driver with variable level displacement and variable output amplitude, which can increase the driving power, adjust the pulse output amplitude as required, and is convenient for integration. [0004] The technical scheme that the present invention takes: [0005] A pulse driv...
