Receiver having a gain-controllable input amplifier
Abstract:
A receiver has an input amplifier (RFAMP) that comprises a signal-voltage amplifier (SVA) and a feedback path (FBP). The signal-voltage amplifier (SVA) provides a voltage gain (VG) from an input node (SESf) to an output node (SON). The voltage gain (VG) is controllable. The feedback path (FBP) provides a transadmittance (GM) from the output node (SON) to the input node (SIN). The transadmittance (GM) is controllable.
Abstract(Chinese):

接收器具有包括信号电压放大器（SVA）和反馈路径（FBP）的输入放大器（RFAMP）。 信号电压放大器（SVA）从输入节点（SESf）向输出节点（SON）提供电压增益（VG）。 电压增益（VG）是可控的。 反馈路径（FBP）提供从输出节点（SON）到输入节点（SIN）的转导（GM）。 转导（GM）是可控的。
