Zusammenfassung:A closed loop amplifier circuit (100) having an on state (202) and an off state (204) is disclosed. The amplifier circuit (100) includes an Automatic Gain Control (AGC) circuit (116). The AGC circuit (116) controls the rate of change in the output power (120) of the amplifier circuit (100) when it changes from the off state (204) to the on state (202) or vice versa. The amplifier circuit (100) also includes a programming circuit (114) that is coupled to the AGC circuit (116). The programming circuit (114) is used to program a desired rate of change into the AGC circuit (116).
