Abstract: The present disclosure is directed a wideband multiphase transmitter with two-point modulation. A transmitter includes a control circuit configured to receive a source signal having amplitude and phase components. Using the phase component, the control circuit generates a frequency control signal and a phase jump signal. The transmitter further includes a phase conversion circuit configured to generate a first phase-modulated signal using the phase component and the frequency control signal. The phase conversion circuit is also configured to adjust the phase of the first phase-modulated signal using the phase jump signal. The first phase-modulate signal and the amplitude component are provided to an amplifier, which generates a transmit signal based thereon.

Abstract: A voltage-controlled oscillator may include an inductor. The inductor may include a first coil coupled to an electronic component. The inductor may include a first coil coupled to the first circuit component, a second coil coupled to the first circuit component via a junction and being in parallel with the first coil, and a shared circuit path coupled to the second circuit component, the first coil, and the second coil, the shared circuit path overlapping the junction. The inductor may be configured to reduce phase noise generated by the electronic component.
