Patent ID: 7805116

Claim:
A transmitter of a wireless device, the transmitter comprising: a ramp generator adapted to receive a gain control input signal and to generate a gain ramp signal based on the gain control input signal, wherein the gain ramp signal indicates a sequence of gains; a digital gain signal generator adapted to generate and incorporate a gain arc into a digital gain signal, wherein the gain arc includes a sequence of digital values that defines an arc, and wherein the sequence of digital values is related to the sequence of gains; a first combiner adapted to receive a digital input signal and the digital gain signal, and to combine the digital gain signal with the digital input signal to generate a pre-compensated digital signal; and the variable gain amplifier, which is adapted to apply the gains indicated in the gain ramp signal to a pre-adjusted analog signal in order to generate a gain-adjusted analog signal, wherein the pre-adjusted analog signal is generated from the pre-compensated digital signal.
