OVERSHOOT CONTROL AND ATTENUATION CIRCUIT FOR A FAST DRIVER

摘要

PURPOSE: An overshoot control and attenuation circuit is provided to generate current spark using a negative feedback so as to correct an overshoot generated when driving an induce load as a fast signal. CONSTITUTION: The overshoot attenuation circuit comprises a first circuit(52) and a load(40). The first circuit(52) is connected to a node(A) and is configured to be connected to a first end of the load(52). The first circuit comprises a voltage-controlled switch for sensing a voltage of the first end of the load. A current is inserted to the first node to correspond to a transient variation of the voltage of the first node.
