Title: Innovations by Oliver J Brennan
Introduction
Oliver J Brennan is a notable inventor based in Oakland, California. He has made significant contributions to the field of impedance measurement circuits, holding two patents that showcase his innovative approach to reducing noise in electronic measurements.
Latest Patents
Brennan's latest patents include "Reduction of noise in impedance measurement circuits" and "Noise cancellation in impedance measurement circuits." The first patent describes a device that allows for the reduction of flicker noise in impedance measurement circuits. This device employs a carrier suppression technique that effectively removes noise artifacts associated with the carrier signal. The method involves sensing the carrier signal at a transmit location and subtracting a weighted version of it at a receive location, utilizing compensation impedances to suppress the carrier signal's sidebands.
The second patent focuses on an impedance measurement circuit designed to measure and detect variations in an impedance under test. This circuit comprises multiple digital-to-analog converters (DACs) that alternate between two modes of operation. By alternating the use of hardware components associated with each DAC, Brennan's design stabilizes errors in impedance measurements over time, enhancing the accuracy of the circuit.
