HIGH-SPEED CAPACITIVE LOAD DRIVER Russian patent published in 2014 - IPC H03F3/34 

FIELD: radio engineering, communication.

SUBSTANCE: high-speed capacitive load driver includes an output stage, the input of which is connected to an input signal source and the output is connected to a load circuit capacitor, a voltage-to-current converter, the potential input of which is connected to the output of the output stage, the potential output is connected to a compensating circuit, the first current output is connected to the input of a first current mirror which is matched with a first power supply bus, the second current output is connected to the input of a second current mirror which is matched with a second power supply bus, current outputs of the first and second current mirrors are connected to the output of the output stage, wherein increments of current of the first and second current outputs of the voltage-to-current converter for corresponding polarities of output voltage are proportional to conductivity of the compensating circuit.

EFFECT: high speed of the driver when operating on a capacitive load and wider operating frequency range thereof.
