Abstract
A transmitter includes a power amplifier (PA) and a direct current (DC) voltage tuning circuit. The PA is arranged for receiving a radio-frequency (RF) clock derived from a clock source, and producing an output signal according to at least the RF clock. The DC voltage tuning circuit is arranged for tuning at least one DC voltage supplied to the PA for pulling mitigation of the clock source. A method of pulling mitigation of a source clock by a power amplifier (PA) includes adjusting a direct current (DC) voltage supplied to the PA.
