INPUT SIGNAL AMPLIFIER |
| 摘要 |
An input signal amplifier includes an inverting amplifier that outputs an input signal, a logic of which is inverted; a first switch. that switches an input, terminal of the inverting amplifier to be grounded or not; and a feedback resistor connected in parallel with the inverting amplifier and including a plurality of resistors with different values of resistance. The feedback resistor includes both a second switch that shorts or opens the feedback resistor via at least one of the resistors and a third switch that shorts or opens the feedback resistor via another of the resistors. |

1. An input signal amplifier. comprising:
an inverting amplifier that outputs an input signal, a logic of which is inverted; a first switch that switches an input terminal of the inverting amplifier between being grounded and not grounded; and a feedback resistor connected. in. parallel with the inverting amplifier and including a plurality of resistors with different values of resistance, wherein the feedback resistor includes both a second switch that shorts or opens the feedback resistor via at least one of the resistors and a third switch that shorts or opens the feedback resistor via another of the resistors. |
