BROADBAND VOLTAGE REPEATER Russian patent published in 2014 - IPC H03F3/50 

FIELD: radio engineering, communication.

SUBSTANCE: broadband voltage repeater comprises an input transistor (1), the control terminal (2) of which is connected to an input signal source (3), the injecting terminal (4) is connected to a first (5) power supply bus through a current-stabilising two-terminal element (6) and is connected to the main output of the device (7), and the charge-collecting terminal (8) is connected to a second (9) power supply bus, wherein the main output of the device (7) is alternating current-shunted by an equivalent load capacitor (10). The circuit includes an additional voltage repeater (11), the input of which is connected to the main output of the device (7), the output is connected to the additional output (12) of the device and through a balancing capacitor (13) to the input of an additional non-inverting current repeater (14), the current output of which is connected to the main output of the device (12).

EFFECT: wide operating frequency range of the broadband voltage repeater when there is a capacitance Cn at the output, which can be reduced for objective reasons, shorter time for establishing a transient process with pulsed variation of the input voltage.
