Latest Patents

One of Jürgen Schäfer's latest patents is a circuit for determining the frequency of a signal. This invention describes a circuit that includes an input for receiving an analog signal, an analog to digital converter, and a digital mixer. The circuit generates a mixing result signal by combining the digital input signal with a single bit binary signal that has a reference frequency. It also features a low pass filter to produce a filtered signal and a measuring circuit to determine the period of the filtered signal. The output provides a value that differs from the frequency of the binary signal by the inverse of the measured period.

Another significant patent by Schäfer is related to resolver-to-digital conversion with a rotation speed offset. This resolver-to-digital converter includes a feedback filter chain loop with a state observer that estimates the rotation speed and angle of an object. It utilizes input sine and cosine signals that are amplitude-modulated to correspond with the rotation angle. Additionally, a feedforward filter chain path is employed to estimate the rotation speed based on the same input signals. The state observer is designed to offset the estimated rotation speed to reduce the settling time of the estimated rotation angle.
