Abstract:
In a time division multiple access transmission device, a power amplifier driver providing a control signal in response to an error signal, the power amplifier driver comprising:a detector (18) having an input coupled to receive a signal representative of a transmission level and coupled to provide a detector signal operating in a first mode, wherein the detector comprises a first detection stage (46, 54, 56) having an input coupled to receive the signal representative of the transmission level, a power supply input coupled to receive a first supply potential and an output coupled to provide the detector signal; and a second detection stage (44, 50, 52) having a power supply input coupled to receive the first supply potential and an output coupled to provide a reference signal; and an error generator (22) coupled to receive the detector signal and a reference signal and coupled to provide a difference signal operating in a second mode to control the transmission level.
