Latest Patents

Johnston holds a patent for a technique titled "Stabilization and Calibration of Precision Electronic Circuit Component." This invention focuses on stabilizing and calibrating precision analog circuit components, such as amplifiers. The method involves using a sample and hold circuit placed in the feedback loop of the component. By periodically coupling the input to a reference voltage while the sample and hold circuit is in sample mode, any offset voltage at the output is automatically canceled. This process is repeated at convenient intervals to maintain the sample and hold circuit's charge and compensate for changes in operating conditions over time. The transfer function of the component can be determined by measuring its response to known input voltages, allowing for accurate output conversion during normal operation.
