    Abstract: The application discloses a differential amplifier with selectable gain. The differential amplifier comprises a pair of input transistors, a first pair of load transistors and a second pair of load transistors. The drain-source-paths of the first pair of load transistors is connected between a reference potential and the two output terminals of the pair of input transistors, while the gates are commonly connected to a control voltage. The drain-source-paths of the second pair of load transistors os connected in parallel to the drain-source-paths of the first pair of load transistors. Through a control circuit, the gates of the second pair of load transistors are either connected to the reference potential (second pair deactivated) or cross coupled to the output terminals of the pair of input transistors (second pair activated) to provide positive feedback. By activating/deactivating the second pair of load transistors, the gain of the differential amplifier is coarsely switched between a high gain mode a low gain mode, while a fine adjustment of the gain can be obtained by altering.

    Abstract translation: 本申请公开了一种具有可选增益的差分放大器。 差分放大器包括一对输入晶体管,第一对负载晶体管和第二对负载晶体管。 第一对负载晶体管的漏极 - 源极路径连接在参考电位和一对输入晶体管的两个输出端之间,而栅极共同连接到控制电压。 第二对负载晶体管的漏极 - 源极路径并联连接到第一对负载晶体管的漏 - 源 - 路径。 通过控制电路,第二对负载晶体管的栅极或者连接到参考电位(第二对被去激活)或交叉耦合到该对输入晶体管的输出端(第二对被激活),以提供正反馈。 通过激活/去激活第二对负载晶体管,差分放大器的增益在高增益模式低增益模式之间粗略切换,而通过改变可以获得增益的微调。

    Abstract: For one disclosed embodiment, an integrated circuit may comprise an internal transmission line in one or more layers of the integrated circuit. The internal transmission line may be coupled to receive a signal from an external transmission line at a first end of the internal transmission line without use of termination circuitry. The internal transmission line may transmit the signal passively to a second end of the internal transmission line. The integrated circuit may also comprise first circuitry having an input coupled to the internal transmission line at a first location of the internal transmission line to receive the signal and second circuitry having an input coupled to the internal transmission line at a second location of the internal transmission line to receive the signal. The second location may be different from the first location. Other embodiments are also disclosed.
