Latest Patents

Fred Weiss holds a patent for a low power charge pump. This charge pump is designed to be enabled only when a loop filter requires updating, which effectively reduces the overall power consumption. The charge pump operates in response to an enable signal generated by a latch. This enable signal is activated by look-ahead signals that are triggered in advance of pulses from either a reference signal or a variable signal. This design allows the charge pump to stabilize before supplying the charge current necessary for updating the loop filter. Additionally, the charge pump is disabled by a reset signal from a phase-frequency detector once the loop filter has been updated. The innovative design includes a current switch that generates source and sink charge currents based on pump-up and pump-down control signals, further enhancing its efficiency.
