Latest Patents

One of Dotzauer's notable innovations is a patent for a **High Accuracy RC Oscillator**. This device incorporates an RC oscillator circuit and features designed to enhance the stability and accuracy of the output frequency. It provides a tunable output frequency and includes a bias circuit that can switch between two modes of operation, one of which exhibits reduced drift in oscillator bias current. Additionally, the device is equipped with drift compensation circuitry that operates in a closed-loop mode, compensating for discrepancies between the oscillator output frequency and a reference frequency. Furthermore, it employs a processor to address temperature-induced drift in the oscillator frequency during open-loop operation based on local temperature readings.

Another important patent from Dotzauer is a **Driver Circuit and Method for Driving an Electronic Component**. This invention facilitates the controlled operation of electronic components, such as laser diodes, by regulating a variable electric current that alternates between at least two distinct levels. The driver circuit is designed to mitigate ringing or transient oscillations that can occur during current switching, utilizing a current mirror with a frequency-dependent mirror amplification factor. To counteract parasitic effects that may cause ringing, components like inductors, resistances, and capacitances are strategically integrated into the circuit design.
