Title: Innovations of Johannes Gerardus Willms

Introduction

Johannes Gerardus Willms is a notable inventor based in Oosterhout, Netherlands. He has made significant contributions to the field of technology, particularly in the development of sensing devices and frequency divider units. With a total of four patents to his name, Willms continues to push the boundaries of innovation.

Latest Patents

One of his latest patents is a sensing device comprising a phase locked loop circuit. This device features an oscillator that provides an oscillator output signal. It includes a power amplifier that generates an amplified output signal based on the oscillator output signal. The amplified output signal contains an interfering signal component at the oscillator frequency. The device also incorporates a measurement circuit to assess offset information regarding the frequency offset between the oscillator frequency and a target frequency. This frequency offset arises from a frequency pulling effect at the oscillator, caused by the interfering signal component. Additionally, the sensing device has a control circuit that utilizes the offset information for trimming the phase locked loop circuit and/or the power amplifier, as well as for determining information regarding an environmental situation at the output of the power amplifier.

Another significant patent by Willms is a programmable frequency divider. This unit receives an oscillating signal and updates a frequency-divided oscillating signal at its output. The frequency divider unit features a first clocked signal inverter that updates a first intermediate signal based on the oscillating signal. It also includes a second clocked signal inverter, where the output of the first inverter connects to the input of the second. The second inverter updates a second intermediate signal, also clocked by the oscillating signal. Furthermore, a continuously operating signal inverter is coupled between the output of the second inverter and the input of the first inverter.
