ADAPTABLE VOLTAGE CONTROL FOR A VARIABLE GAIN AMPLIFIER
摘要：
A method and apparatus for adaptively controlling a variable gain amplifier (VGA). The operation of the VGA is separated into a low gain mode and a high gain mode and the mode in which the VGA is currently operating in is adaptively sensed. A threshold voltage is compared to a control voltage of the VGA; if the VGA is currently operating in the low gain mode and the control voltage is higher than the threshold voltage, the VGA is switched from the low gain mode to the high gain mode; and if the VGA is currently operating in the high gain mode and the control voltage is lower than the threshold voltage, the VGA is switched from the high gain mode to the low gain mode.
摘要（中）：

一种用于自适应地控制可变增益放大器（VGA）的方法和装置。 VGA的操作被分为低增益模式和高增益模式，并且自适应地感测VGA当前正在操作的模式。 将门限电压与VGA的控制电压进行比较; 如果VGA当前处于低增益模式并且控制电压高于阈值电压，则VGA从低增益模式切换到高增益模式; 如果VGA当前处于高增益模式并且控制电压低于阈值电压，则VGA从高增益模式切换到低增益模式。
