The present invention employs gain compensation such that when the amplifier is in the clean mode, the gain is at a selected level and when the amplifier is in the lead mode gain is decreased. In one embodiment a selectable brightness control is employed to raise the high frequency response ...
I have not tested such a configuration, but see no reason why it would not work. There are a couple of things to keep in mind. Gain accuracy will depend on many more resistors (including switch ON-resistance) than a typical op amp circuit. Also, the switch capacitances will play...
