| Zusammenfassung: | Disclosed herein are embodiments of a wide bandwidth attenuator circuit having a tunable gain and tunable input impedance. In some embodiments, the wideband attenuator circuit comprises a serial capacitor shunted to ground by a plurality of circuit slices that are connected in parallel and switchably coupled to the output node of the attenuator. Each circuit slice has a tunable resistor that can be set to a conductive state ("enabled") or a high impedance state ("disabled") The number of enabled circuit slices that are connected in parallel may be used to program the attenuator gain and the attenuator impedance. |
