Latest Patents

Among Kitayama's latest patents are two remarkable inventions:

1. **Clock Generating Circuit and Signal Processing Device**

This invention features a clock generating circuit with a unique design that includes a dividing unit and a distribution unit. The divided clock, which is generated by this circuit, has a frequency that is a fraction (1/N) of a reference clock frequency, where N is an integer of two or more. The distribution unit separates the output into two paths: one that delivers a clock identical to the reference and another that includes the dividing unit, which integrates amplifiers and a correction circuit to ensure signal integrity.

2. **Signal Level Adjusting Device and High-Frequency Apparatus**

This invention aims to enhance performance in frequency synthesizers. It includes a variable attenuator, a detector, and a control unit that adjusts the attenuation amount based on a detection voltage. A key aspect of this design is the integration of a low-pass filter designed to mitigate unwanted spikes when the output of the digital/analog converter changes. This careful engineering ensures that operational efficiency is maintained by allowing for optimal control of the signal levels.
