Title: The Innovations of Carlos P De Araujo
Introduction
Carlos P De Araujo is a notable inventor based in Colorado Springs, CO. He holds a total of 4 patents that showcase his contributions to the field of technology and engineering. His work primarily focuses on advancements in sensor technology and integrated circuits.
Latest Patents
One of his latest patents is a pyroelectric sensor designed to determine the charge output of a ferroelectric scene element. This sensor measures the hysteresis loop output of the scene element multiple times during a specific time frame at the same temperature. An external AC signal is applied to switch the polarization of the ferroelectric scene element, and charge integration circuitry is utilized to measure the charge from the scene element. The ferroelectric material used is strontium bismuth tantalate, or a derivative thereof, positioned between top and bottom electrodes. The polarization difference between the reference element and the scene element is measured and summed to produce a signal output voltage.
Another significant patent is for a ferroelectric integrated circuit. This innovation features an oversized ferroelectric capacitor positioned against the contact hole to the MOSFET source/drain in a DRAM. A barrier layer made from various materials, including titanium nitride and platinum, is placed between the ferroelectric layer and the source drain. This design allows for improved performance and efficiency in memory devices.
