US 2026/0012151 A1 · STAGGERING GAIN ADJUSTMENTS OF AMPLIFIERS

Abstract

Adjustments to gain levels, associated with amplifiers, including partial adjustments to gain levels associated with certain amplifiers can be controlled and performed in accordance with an amplifier gain adjustment sequence. In response to determining that an overall gain level associated with a group of amplifiers, comprising first, second, and third amplifiers, is to be reduced, AGC component can determine whether a third gain level associated with the third amplifier is at a minimum. In response to determining that third gain level is at minimum, AGC component can determine which of a first gain level associated with the first amplifier and a second gain level associated with the second amplifier is to be partially reduced, in accordance with the amplifier gain adjustment sequence that, in part, specifies alternating between partial first gain level reductions associated with the first amplifier and partial second gain level reductions associated with the second amplifier.
