Title: Paul Mateman: Innovator in RF Technology

Introduction

Paul Mateman is a notable inventor based in Millingen aan de Rijn, Netherlands. He has made significant contributions to the field of radio frequency (RF) technology, holding a total of 8 patents. His work focuses on high-speed RF circuits and sample-and-hold circuit arrangements, showcasing his expertise in electronic design.

Latest Patents

Among his latest patents, Mateman has developed a high-speed RF divider. This invention features clock divider designs that utilize inverters and clocking circuits arranged in a serial ring formation. In one embodiment, the design employs only NMOS transistors in the inverters and PMOS transistors in the clocking circuits, resulting in a structure that uses just 12 transistors. The input can be directly coupled to a voltage-controlled oscillator (VCO) output, minimizing loading as each VCO output connects to only two transistors. Another embodiment includes clocked inverter stages in a serial ring configuration, enhancing speed by using the RF clock at the outer side of the inverters.

Additionally, Mateman has created a sample-and-hold circuit arrangement that operates at maximum speed when the sampling phase is significantly shorter than the holding phase. This design allows the device driving the sampling capacitor to be disconnected most of the time. The method utilizes the holding phase to store the full charge required by the sampling capacitor, ensuring that when the sampling capacitor is switched to the driver, it is almost instantly charged to the required voltage.
