Patent ID: 8681838

Claim:
An electronic device comprising: a transmitter comprising a baseband input for at least one baseband signal, at least one mixer downstream from said baseband input, a phase-locked loop (PLL) comprising a voltage controlled oscillator (VCO) and a phase detector coupled thereto, said VCO coupled to said at least one mixer and operating at a multiple of a desired frequency of a transmit signal, at least one power amplifier downstream from said at least one mixer, generating at least one aggressing signal that would otherwise generate an output pull of said VCO, causing transmit distortion on the transmit signal; a receiver coupled to said at least one power amplifier and comprising a sense input configured to receive the transmit signal; and a VCO pulling compensation circuit coupled to said baseband input and configured to compensate the at least one baseband signal for the transmit distortion based upon the sensed transmit signal, said VCO pulling compensation circuit comprising an exponential block configured to raise the transmit signal to an exponent equal to the multiple of the desired frequency.
