摘要:
Systems and methods are provided in which an offset phase-locked loop (PLL) system can be configured as part of a radio frequency transmitter. The PLL can include a phase detection circuit including a first input configured to receive an information signal and a second input configured to receive a feedback signal; a charge pump including an input coupled to the phase detection circuit and an output; a filter including an input coupled to the output of the charge pump; a voltage-controlled oscillator coupled to the charge pump and including an LC tank circuit comprising an inductive element and a capacitive element, wherein the inductive element of the LC tank circuit comprises the antenna; and a feedback path.
