SWITCHED GAIN AMPLIFIER CIRCUIT |
摘要 |
An amplifier chain that switches between a saturated mode of operation and a linear mode of operation comprises at least two amplifier stages. A switch is associated with the first amplifier stage and dampens the gain of the amplifier chain when the switch is closed. In a first embodiment, this is done by bypassing the first amplifier stage. In second and third embodiments, this is done by providing a feedback loop to the first amplifier stage. Dynamic device scaling and changing the bias may also be used to affect the performance of the amplifier chain.
