Introduction

Christian Steffen Birk is an accomplished inventor based in Innishannon, Ireland. He holds a total of 6 patents that showcase his expertise in the field of electronics and circuit design. His innovative contributions have made a significant impact in the industry.

Latest Patents

One of his latest patents is an analog multiplexer. This device is designed for sampling an input voltage that may exceed the upper supply voltage. The analog multiplexer consists of multiple input switch circuits and a shorting switch circuit. The input switch circuits utilize n-type or p-type laterally diffused field effect transistors (NLDFETs or PLDFETs). Notably, at least one of the input switch circuits incorporates a level shifting switch circuit, enabling it to sample input voltages greater than the upper supply voltage. Additionally, the shorting switch circuit at the output is equipped with a capacitively coupled gate drive circuit, which allows it to short a first differential output to a second differential output after sampling the input voltage.

Another significant patent involves capacitance measurement. This invention provides a method for measuring an unknown capacitance of a device. The method includes driving a test signal to a circuit system that features a current divider formed by the device with unknown capacitance and a reference capacitor. It mirrors the current developed in the reference capacitor to a second circuit system that includes a measurement impedance. By measuring the voltage within the second circuit system, the capacitance of the unknown device can be derived based on the measured voltage, the capacitance of the reference capacitor, and the measurement impedance.
