| Zusammenfassung: | A dynamic amplifier includes an amplifier configured to differentially amplify first and second input signals to generate first and second output signals, a bias circuit, and a variable impedance circuit. The bias circuit is connected between a first power node configured to supply a first source voltage and the amplifier, and configured to apply bias to the amplifier. The variable impedance circuit is connected between the amplifier and a second power node configured to supply a second source voltage that is lower than the first source voltage. The variable impedance circuit is configured to adjust amplification gain of the amplifier, by adjusting impedance based on a magnitude of one among the first and second input signals and the first and second output signals. |
