Summary: | PROBLEM TO BE SOLVED: To provide an electronic component, an information processing device, and an electronic component control method that implement a reduced mounting area.SOLUTION: A first amplification section amplifies one of differential signals. A second amplification section amplifies the other of the differential signals. ADCs 107, 108 measure voltages of a first output signal output from the first amplification section and a second output signal output from the second amplification section. On the basis of the voltages measured by the ADCs 107, 108, a control circuit 109 controls either or both of current and resistance values of the first amplification section such that a common voltage of the first output signal approximates to a common voltage of the second output signal.
【課題】実装面積を縮小した電子部品、情報処理装置及び電子部品制御方法を提供する。【解決手段】第1増幅部は、差動信号の一方の信号を増幅する。第2増幅部は、差動信号の他方の信号を増幅する。ADC107,108は、前記第1増幅部から出力される第1出力信号及び前記第2増幅部から出力される第2出力信号の電圧を測定する。制御回路109は、ADC107,108により測定された電圧を基に、第1出力信号のコモン電圧と第2出力信号のコモン電圧とが近似するように、第1増幅部の電流又は抵抗値のいずれか一方もしくは双方を制御する。【選択図】図2 |
