Title: Lee L Evans: Innovator in Analog-to-Digital Conversion Technology
Introduction
Lee L Evans is a prominent inventor based in Atherton, California, known for his significant contributions to the field of analog-to-digital conversion technology. With a total of 5 patents to his name, Evans has developed innovative solutions that enhance the performance and accuracy of electronic devices.
Latest Patents
Among his latest patents is the "Dual slope analog-to-digital converter with automatic, short cycle range." This invention features a dual slope analog-to-digital converter that automatically determines the short cycle range. The time period of the signal integration phase is adjusted to accommodate various input signal ranges. The converter can switch quickly from one range to another until the correct range is found, eliminating the need for an 'out of range' reading. Additionally, it achieves normal mode rejection of 60 Hz noise across all timing ranges.
Another notable patent is the "High speed integrating analog-to-digital converter." This integrating type converter boasts improved time measurement capabilities and a very fast conversion cycle. It operates by integrating an analog input signal for a predetermined time and then deintegrating the signal until its output crosses zero. The time taken for the integrator to cross zero is measured by a digital clock, allowing for precise measurements. By utilizing multiple multiplication and deintegration cycles, the resolution of the time measurement can be significantly increased, achieving a 12-bit measurement with fewer clock pulses compared to prior art converters.
