FIELD: radio engineering, communication.SUBSTANCE: optical radiation receiver includes a radiation sensor (1), connected through alternating current to the input of the device (2), connected to the inverting input of a first (3) differential amplifier, the non-inverting input of which is connected to a common power supply bus (4), a feedback resistor (5) connected between the output of the first (3) differential amplifier, connected to the output of the device (6), and the inverting input of the first (3) differential amplifier. The inverting input of the first (3) differential amplifier is connected to the inverting input of an additional differential amplifier (7), the non-inverting input of which is connected to the common power supply bus (4), the non-inverting input of the first (3) differential amplifier is connected to the common power supply bus (4) through a first (8) additional resistor and is connected to the output of the additional differential amplifier (7) through a second (9) additional resistor, wherein a third (10) additional resistor is connected between the input of the device (2) and the output of the additional differential amplifier (7).EFFECT: faster operation with radiation sensors in form of photodiodes, having considerable parasitic capacitance.4 cl, 6 dwg |
