Title: The Innovations of James Alvernaz
Introduction
James Alvernaz is an accomplished inventor based in West Greenwich, Rhode Island. He holds a total of 3 patents that showcase his expertise in electrical engineering and circuit design. His innovative contributions have made a significant impact in the field.
Latest Patents
One of his latest patents is the Precision Hysteresis Generator. This device provides a comparator with a precision hysteresis reference input. The output of the comparator controls a switch that determines whether a reference current is applied to a resistor. The resistor connects between a reference voltage and the input to the comparator. A buffer amplifier supplies the reference voltage to the resistor. The reference current is derived from a second resistor connected between the output of the buffer amplifier and the input of a current mirror. The current mirror applies its output current to the first resistor. Additionally, a diode may be inserted to ensure that the hysteresis voltage generated is substantially temperature independent. Another notable patent is the Negative Input Voltage Comparator. This comparator compares a negative input voltage signal against a positive voltage signal in a circuit, such as an integrated circuit. The negative input voltage signal is effectively isolated from the circuit by a series resistor in the base-emitter circuit of a transistor connected in the output leg of a current comparator.
