With a total of 11 patents to his name, Arcus has demonstrated a commitment to innovation and technological advancement.

Latest Patents

One of his latest patents is for a low power charge pump. This charge pump is designed to control current flow at an output node in response to input signals. A plurality of control signals are generated based on these input signals, which operate to control the timing and duration of current flows within the charge pump, thereby reducing power consumption. The design allows for the conductivity of a first path between a power supply and the output node, as well as a second path between the output node and ground potential, to be varied based on the control signals. Additionally, this charge pump can be integrated into a phase-locked loop (PLL), where the input signals are produced by a phase/frequency detector, and the current flow at the output node controls an oscillator element.

Another significant patent involves a PLL with a built-in filter-capacitor leakage tester, which includes a current pump and comparator. This innovation allows for the testing of a filter capacitor within a PLL using a built-in test circuit. During testing, the PLL's charge pump is deactivated while a test-current source is activated to supply a test current to the PLL filter capacitor. The test comparator signals a good test result when the capacitor's voltage rises above a reference voltage, indicating that the capacitor is functioning properly.
