Latest Patents

Among his latest patents, Brown has developed a system for the linearization of FET channel impedance for small signal applications. This innovative system effectively applies a mathematical substitution to the characteristic V/I equation for FET devices operating in the ohmic region. By canceling the non-linear term that produces distortion, it significantly improves the realizable channel impedance linearity. The system includes a method to sum a specific portion of the information signal applied to the FET with the gate controlling voltage, resulting in enhanced linearity when applied to the FET gate terminal.

Another notable patent is his distortion reduction system for audio devices. This system allows a speaker driver to significantly increase its average acoustic output power without degrading audio signal quality. It operates independently of the power supply voltage by detecting voltage differences between the instantaneous peak amplified audio signal and the power supply voltages. The system provides gain control signals to the driver circuit to maintain audio signal integrity while maximizing the average RMS value.
