Latest Patents

One of Jennings' latest patents is titled "Dual path phase locked loop (PLL) with digitally programmable damping." This invention describes a method and apparatus for controlling damping and bandwidth in a PLL. The loop filter is designed with a dual path for charge pump current, allowing for precise control over the PLL's bandwidth by adjusting the gain of a proportional current path. An integral current path is also included, featuring a gating circuit that digitally controls the effective integral charge pump current. This innovation ensures that damping and peaking of the PLL are accurately managed.

Another significant patent by Jennings is "Frequency and phase correction in a phase-locked loop (PLL)." This system incorporates a phase frequency detector and two charge pumps that generate currents based on frequency and phase differences. The current summer combines these currents to produce a control current for a current-controlled oscillator (CCO), which generates oscillating signals. This invention enhances the frequency and phase correction capabilities of PLL systems, making them more efficient and reliable.
