Title: The Innovations of Steven E Grieco
Introduction
Steven E Grieco is a notable inventor based in Albuquerque, NM (US). He has made significant contributions to the field of electronics, particularly in the development of ceramic filters and temperature compensation circuits. With a total of 2 patents, Grieco's work has had a meaningful impact on the industry.
Latest Patents
Grieco's latest patents include a Multi-resonator ceramic filter and a method for tuning and adjusting it. This innovative ceramic block filter employs a novel tuning process that avoids the need for etching or abrading the plating on the top surface of the block. The blocks are initially prepared from a batch of ceramic material with a height intentionally longer than desired, resulting in a filter center frequency that is slightly lower than intended. An artwork mask is then used to apply an electrically conductive material to the top surface of the block. After measuring the center frequency and resonator length, the block is lapped to the new resonator length, and conductive material is applied to the lapped bottom surface.
Another significant patent is the temperature compensation circuit for an oscillator with a parabolic frequency response concerning temperature. This improved circuit includes a time-dependent ramp signal and an AC integrator that converts the ramp signal into single-sided parabolic voltage functions. The resulting voltage functions are sampled with respect to a time base at selected times corresponding to ambient temperatures.
