Tsutomu Kamoto is a notable inventor based in Kanagawa, Japan. He is recognized for his contributions to the field of frequency divider systems. His innovative work has led to the development of a unique fractional-N frequency divider system.

Latest Patents

Kamoto holds a patent for a fractional-N frequency divider system. This system generates an output signal with a frequency that is the input signal divided by a desired frequency division ratio (N+A/M). In this equation, N is an integer, and A/M is a fraction where A is less than or equal to M. The system includes a programmable frequency divider that receives the input frequency and provides a divided frequency based on an externally supplied division ratio. The design features a selector that supplies one of the externally supplied integers to the divider according to a selection signal. Additionally, it incorporates a fractional part set with two counters and a logic circuit that manages the selection process.
