Latest Patents

Dawson's latest patents include "Automatic phase alignment for high-bandwidth Cartesian-feedback power amplifiers" and "Low-complexity adaptive controller." The first patent focuses on an automatic phase alignment circuit for a Cartesian feedback amplifier, where the phase error is regularly monitored. This invention provides true and continuous phase alignment by utilizing a relationship between up-converted and down-converted signals. It also addresses phase error caused by DC-offset interference, which can affect the outputs of various analog functional blocks. The second patent describes an adaptive feedback controller designed to minimize the error control signal defined by the difference between a command signal and the output signal of a controlled device. This controller features a step generator circuit that produces a control signal in the shape of a ramp, with an adaptive slew rate computation circuit that adjusts the slew rate based on the input signal's variability.
