Latest Patents
One of Nystrom's latest patents is focused on automatic gain control. This method involves controlling the gain of an amplifier by amplifying received signals to produce amplified signals. The process includes generating down converted signals from these amplified signals and adjusting their amplification based on a gain control signal. Additionally, the method allows for varying the time constant of the gain control signal based on parameters associated with the down converted signals.
Another significant patent by Nystrom pertains to filter trimming. This invention utilizes an adjustable phase shifter to generate a phase shifted reference signal by introducing a phase shift in a reference signal. A phase detector identifies the phase difference between the reference signal and the phase shifted reference signal. The control signal generator then produces multiple control signals, enabling the adjustable phase shifter to modify component values. This adjustment ensures that the phase difference reaches a specified value, enhancing the performance of the analog filter.
