Design and Fabrication of Uncooled Thermoelectric Infrared Detectors
(Oklahoma State University, 2011-12-01)Described is an uncooled surface-micromachined thermoelectric (TE) infrared detector that features P-doped polysilicon/Nichrome (Cr20-Ni80) as the thermocouple material pair embedded in Parylene-N, which isolates the hot ... -
Frequency stability in thin-film piezoelectric-on-substrate oscillators
(2013-12)For many years, crystal oscillators have been used as the de facto frequency reference in almost all electronic platforms because they offer excellent stability and superior phase noise. This is mainly due to the high ... -
Low-impedance Thin-film Aln-on-diamond Lateral-extensional Resonators
(Oklahoma State University, 2011-12-01)The focus of this thesis is the design and fabrication of thin-film piezoelectric-on-diamond resonators to have very low insertion loss values. Ultrananocrystalline films with different Young's modulus were used as the ... -
Thin Film Piezoelectric on Substrate Resonators Electrical Characterization and Oscillator Circuit Design
(Oklahoma State University, 2011-12-01)Electronic systems require at least one reference signal to enable system synchronization. Oscillators and resonators are frequency selective devices that generate a desired reference signal for the systems. MEMS frequency ...
