Latest Patents

Roche's latest patents include a "Method and apparatus for pulse generation." This invention provides a pulse generator that creates a pulse train by mixing pulses from two clocks with different frequencies. The resulting pulse train has an effective frequency that lies between the two original frequencies. A multiplexer is utilized to select which clock's pulses are output, allowing for control over the target frequency. This pulse generator can be employed as a clock for a charge pump.

Another significant patent is focused on "Control techniques for motor-driven systems utilizing back-EMF measurement techniques." This invention describes a method and apparatus for automatic resonance detection in motor-driven mechanical systems, such as voice coil motors (VCMs). The automatic resonance detector is integrated with the driver on the same circuit, dynamically determining the natural resonant frequency of the VCM by measuring the back electromotive force (BEMF) and analyzing the slope of the BEMF signal.
