EXCITATION CIRCUIT OF CAPACITANCE LOAD, AND DISPLAY DEVICE INCLUDING IT Russian patent published in 2012 - IPC H03K17/687 

FIELD: electricity.

SUBSTANCE: excitation circuit of capacitance load includes voltage comparing unit; excitation control unit; two-stroke output unit including charging diagram which charges the capacitance load connected to output contact on the basis of charge control voltage, and discharging diagram which discharges the capacitance load on the basis of discharge control voltage; at that, excitation control unit operates the charging and discharging diagrams selectively so that output voltage becomes equal to input voltage; and communications between them.

EFFECT: creation of small-scale excitation circuit of capacitance load with low power consumption, which is stable to the process change.
