CURRENT-TO-VOLTAGE CONVERSION CIRCUIT, RECEPTION APPARATUS, AND IMAGING SYSTEM |
摘要 |
Provided is a current-to-voltage conversion circuit, including: an input/output node configured to input a current signal including a direct current component and an alternating current component, and to output a voltage based on the current signal; an amplification unit configured to input the voltage of the input/output node; an extraction unit configured to output a voltage based on a direct current component of a voltage output from the amplification unit; a first current supply unit configured to supply a current based on the voltage output from the extraction unit to the input/output node; and a second current supply unit configured to supply a current based on the alternating current component of the current signal to the input/output node. The current supplied by the second current supply unit corresponds to a difference between a current of the current signal and the current supplied by the first current supply unit. |

1. A current-to-voltage conversion circuit, comprising:
an input/output node configured to input a current signal including a direct current component and an alternating current component, and to output a voltage based on the current signal; an amplification unit configured to input the voltage of the input/output node; an extraction unit configured to output a voltage based on a direct current component of a voltage output from the amplification unit; a first current supply unit configured to supply a current based on the voltage output from the extraction unit to the input/output node; and a second current supply unit configured to supply a current based on the alternating current component of the current signal to the input/output node, wherein the current supplied by the second current supply unit corresponds to a difference between a current of the current signal and the current supplied by the first current supply unit. |
