BROADBAND ATTENUATOR FOR HIGH-SPEED ANALOGUE AND ANALOGUE-DIGITAL INTERFACES Russian patent published in 2014 - IPC H01P1/22 

FIELD: radio engineering, communication.

SUBSTANCE: broadband attenuator for high-speed analogue and analogue-digital interfaces comprises a first resistor (3), an input voltage source (4) connected via alternating current between a common bus (5) and the input of the device (1), a second resistor (6) connected via alternating current between the output of the device (2) and the common bus (5), equivalent capacitance of a load (7), connected via alternating current between the output of the device (2) and the common bus (5), a non-inverting voltage follower (8), a non-inverting current follower (10), and the two-terminal element of a correction circuit (11) is connected between the output of the non-inverting voltage follower (8) and the input of the non-inverting current follower (10).

EFFECT: wider operating frequency range of the device and faster operation thereof when working with high-amplitude pulsed signals.
