| Zusammenfassung: | An amplifier topology achieves enhances DC gain to improve linearity while maintaining a good signal to noise ratio. The amplifier includes an amplifier output stage that supplies an amplifier output signal. The amplifier also includes a sense amplifier that augments the output stage. The sense amplifier is coupled to the amplifier input to control current through the output stage in order to achieve reduced voltage variation at the amplifier input as a function of the amplifier output signal voltage as compared to a basic common source amplifier and thereby enhances DC gain of the amplifier. |
