Abstract
A pulse driver with variable level shift and variable output amplitude belongs to the technical field of pulse electronic circuits, and properly speaking, the pulse driver relates to a topological structure of a driving circuit in an electronic circuit. The pulse driver is formed as follows: two triodes and a resistor form two basic electronic circuits; one of the basic circuits is set as a paraphase follower, from which a first voltage reference point is led; and the other one is connected into an emitter follower, from which a second voltage reference point is led. The structure of the pulse driver is as follows: two basic electronic circuits are communicated with each other in the forward direction through a diode; and the two voltage reference points are independent and not mutually connected. The utility model has the benefits that the normal triodes and resistor are adopted on the circuit to realize the reference level shift between the driving circuit and the driven circuit, and meanwhile the pulse driver can conveniently adjust the amplitudes of output pulses, have great output power and facilitate the integration. The utility model provides the pulse driver for the market, which has the advantages of convenient mass production, low price, and applicability to various electronic fields.
