Abstract

In order to eliminate or greatly reduce ringing excited by current commutation in a CRT line scan circuit, the active node and ground node connections of the circuit are made to two parallel metal plates separated by a dielectric film. Intercomponent connections are kept to a minimum by mounting the components directly on the active node plate which also acts as a heat sink. By this means, internal inductances causing the ringing are reduced. Further, the inductance associated with capacitor connections may be reduced by using the distributed capacitance of the plates to provide at least a portion of the required circuit capacitance.
