Abstract:
1. A method for controlling a circuit within a transmitter, the method comprising: canceling a zero input offset voltage from an output of a level detector; calibrating transmitter output signal strength over a range of input voltage values utilizing a known temperature-and-supply-voltage-independent voltage level by an on-chip voltage-controlled oscillator signal generator and the level detector by comparing a signal generated by said on-chip voltage-controlled oscillator signal generator to a signal received from an amplifier in the transmitter; generating a corrected transfer function to control transmit power, wherein the corrected transfer function characterizes non-linearity in voltage measured by the level detector versus the signal received from the amplifier; and utilizing the corrected transfer function to set output transmit power of the transmitter.
