Latest Patents

One of Matson's latest patents is the "Multiple slope analog-to-digital converter." This invention includes numerous improvements that eliminate timing and non-linearity errors, which can accumulate due to extensive switching operations during an integrate cycle. The ADC features an integrator and a comparator, where an input voltage is applied to a summing node during the integrate cycle. Positive and negative reference currents are selectively applied to this summing node by a controller that monitors the comparator's output. This design limits the voltage magnitude at the output of the integrator. During the de-integrate cycle, the input voltage is disconnected, and progressively shallower ramps are measured with a high-speed clock to enhance resolution and accuracy. The comparator incorporates slight hysteresis to separate the switching thresholds for positive and negative ramps. Additionally, the design minimizes current surges and controls the order of switch operations to eliminate charge injection effects. The system allows for the use of stable, off-the-shelf components, making it cost-effective.

Another significant patent is the "Fiber optic guard crossing of circuits having analog and digital sections." This invention establishes electrical isolation and minimizes capacitive coupling between analog and digital circuit sections. It utilizes optical fiber cables to connect circuit boards or partitioned regions of a common circuit board. Electrooptical transmitters and receivers are coupled to these optical fibers, allowing for efficient signal transmission. In one embodiment, bit serial signals are transmitted through a single optical fiber cable, while another embodiment uses multiple optical fibers for parallel bit signals.
