Patent number: 10756625Abstract: An integrated module of acoustic wave device with active thermal compensation comprises a substrate, an acoustic wave filter, an active adjustment circuit and at least one variable capacitance device. The acoustic wave filter comprises a plurality of series acoustic wave resonators formed on the substrate, at least one shunt acoustic wave resonator formed on the substrate and a thermal sensing acoustic wave resonator. Each of the variable capacitance device is connected in parallel to one of the series and shunt acoustic wave resonators. The active adjustment circuit outputs an active thermal compensation signal correlated to a thermal variation sensed by the thermal sensing acoustic wave resonator to the variable capacitance device. The active thermal compensation signal induces a capacitance variation of the variable capacitance device such that the impact of the thermal variation to the acoustic wave device is compensated.Type: GrantFiled: June 27, 2017Date of Patent: August 25, 2020Assignee: WIN SEMICONDUCTORS CORP.Inventors: Re Ching Lin, Shu Hsiao Tsai, Cheng Kuo Lin, Chih-Feng Chiang, Fan Hsiu Huang, Tung-Yao Chou

Patent number: 10103624Abstract: A thermal sensor circuit comprises a conversion circuit which is one of a buck DC-DC converter circuit and a boost DC-DC converter circuit, wherein the conversion circuit comprises an inductor and an output terminal. A thermal sensor senses a thermal variation correlated to a capacitance variation of the thermal sensor. The capacitance variation induces an internal parasitic capacitance variation of the inductor which is connected in parallel to the thermal sensor and results a variation of an energy stored in the inductor. Hence a variation of a converted circuit signal outputting by the output terminal is caused, wherein the variation of the converted circuit signal is correlated to the thermal variation.Type: GrantFiled: June 27, 2017Date of Patent: October 16, 2018Assignee: WIN Semiconductors Corp.Inventors: Re Ching Lin, Fan Hsiu Huang, Tung-Yao Chou, Cheng Kuo Lin, Shu Hsiao Tsai, Chih-Feng Chiang

Patent number: 7489872Abstract: The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.Type: GrantFiled: September 24, 2004Date of Patent: February 10, 2009Assignee: National Central UniversityInventors: Yi-Jen Chan, Fan-Hsiu Huang, Hsin-Pin Wang, Dong-Ming Lin, Mu-Tao Chu, Shin-Ge Lee, Shun-Tien Lee
