Latest Patents

Hansen holds a patent for a technology titled "Residual Mode Phase Locked Loop." This invention describes a phase locked loop that subtracts an estimated signal from an input signal, operating on the residual signal. The residual signal is demodulated and applied to a controlled oscillator, producing feedback signals that approximate the sine and cosine of the input signal. The cosine feedback signal is multiplied by the residual signal, resulting in a frequency correction signal. Additionally, the sine feedback signal is multiplied by the residual signal to produce an estimated signal that is both amplitude and frequency controlled. This innovative approach effectively reduces the residual signal to near zero, enhancing the accuracy of signal processing.
