Latest Patents

One of Köllmann's latest innovations is the Analog Phase Selection Test System. This system includes a phase-shift to duty-cycle converter and a low pass filter. The phase-shift to duty-cycle converter has a first input for a reference clock and a second input for a phase-shifted clock that is phase-shifted relative to the reference clock. The low pass filter is coupled to the output of the phase-shift to duty-cycle converter, providing an output signal. In some implementations, the converter includes a simple logic gate and a reset-set flip flop, enhancing its functionality.

Another significant patent is related to a Radar System. This system comprises multiple radar transceiver modules, each synchronized with a clock signal generated by a leader transceiver module. The leader module provides a first clock signal at a specific frequency to each follower module. Each module includes a phase locked loop (PLL) clock signal generator, which outputs phase-shifted clock signals, ensuring precise synchronization across the system.
