Abstract: This disclosure is directed towards systems and methods that improve bandwidth shifting operations of an ADPLL without losing a lock of the ADPLL and having the benefit of being able to change the bandwidth an unlimited amount of times. Indeed, a processor may transmit amplification parameters to the ADPLL to implement a bandwidth shift. The shift may occur in response to a enable signal, such as a gear trigger control signal (gear_retime signal) or a enable signal generated to cause alignment of the shifting with a clock signal (e.g., enable signal generated by AND logic gates). These systems and methods described herein many enable multiple bandwidth changing operations to occur without compromising the complexity and footprint of the system.

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.
