Introduction

Andreas Friesen is an inventor associated with Dortmund, Germany. His patent work includes a device and method designed to inhibit substrate current in an integrated-circuit semiconductor substrate.

Latest Patents

Friesen is credited with 1 patent: “Device and Method for Inhibiting a Substrate Current in an IC Semiconductor Substrate.” The invention describes devices and methods that detect the potential at a contact in a CMOS circuit and compare it with a reference value. When the detected potential is at or below that value, the circuit connects the contact to a leakage node, diverting current so it does not flow to ground through a parasitic lateral bipolar structure. The leakage node may connect to the reference-potential line or to another line with a higher potential.
