Monolithic integrated cct. - designed for application without compensation current of DC or AC voltage to cct. point at any potential

摘要

Two constant current sources are connected to the circuit point. They deliver currents of the same intensity but of opposite polarities with respect to the point. The d.c. or a.c. voltage is applied to the onput of at least one of the two constant current sources. The constant current sources are parts of current mirror circuits, with at least one output current equal and opposite to at least one output current of a further current mirror circuit. The circuit can be used for application of the N-S correction signal to the output of the vertical deflection pulse generator in colour.
