Title: Innovations of Ali Isaac
Introduction
Ali Isaac is a notable inventor based in Bristol, GB. He has made significant contributions to the field of radio frequency technology, holding a total of 4 patents. His work focuses on enhancing the performance and efficiency of radio frequency tuners and related devices.
Latest Patents
Among his latest patents is a radio frequency tuner that features one or more tracking filters ahead of at least one frequency changer. This innovative tuner includes a controller with a filter alignment mode and a reception mode. Each filter is equipped with resonant networks that consist of an inductance and a digitally controlled switched capacitor network for selecting the network resonant frequency. In the alignment mode, the controller determines the difference between the nominal and actual capacitances to achieve a known resonant frequency, allowing for the calculation of a correction factor for the capacitor network. This correction factor is utilized during normal reception by the tuner.
Another significant patent is a variable signal delaying circuit, which comprises an analog delay line with a control input for managing the variable delay. A phase detector compares the input and output signals of the delaying circuit, supplying an output signal to a charge pump and integrator. The arrangement produces pulse streams of varying widths, with control logic selecting the optimal pulse stream to minimize changes in the output. This technology is particularly useful for maintaining minimum phase imbalance in I and Q signal paths of a quadrature frequency converter.
