Patent number: 10213785Abstract: Method and apparatus for amplifying a target nucleic acid sequence of a reaction mixture in a Polymerase Chain Reaction (PCR). The method includes contacting the reaction mixture with EMR frequency absorbing particles formed from a material having a transition metal, transition metal oxide or a transition metal hydroxide, or a nitride, a phosphide or an arsenide of a Group III metal doped with the transition metal or a transition metal oxide, or silicon dioxide doped with the transition metal, transition metal oxide, or transition metal hydroxide; and irradiating the EMR absorbing particles with EMR having a frequency of about 200 kHz to 500 THz to amplify the target nucleic acid sequence, wherein the Group III metal is any one of Al, Ga, and In, and the transition metal is any one of Mn, Fe, Co and Cu.Type: GrantFiled: August 31, 2015Date of Patent: February 26, 2019Assignee: NATIONAL CHENG KUNG UNIVERSITYInventors: Dar-Bin Shieh, Chih-Chia Huang, Chen-Min Chang, Tsung-Ju Li, Po-Yang Chang, Ming-Chi Hsieh

Patent number: 9509419Abstract: A communication circuit includes a receiver path, a frequency translating loop filter and a signal source circuit. The frequency translating loop filter includes an auxiliary mixer, and a frequency translating filter backend circuit such as a filter. The signal source circuit can be shared with a transmitter path. When the receiver path receives an external signal, the auxiliary mixer and the frequency translating filter backend circuit perform high-frequency filtering. When the receiver path need not receive the external signal, the auxiliary mixer up-converts a low-frequency auxiliary signal provided by the signal source circuit to a high-frequency domain, and the up-converted signal is received by the receiver path. Thus, an operation parameter of the receiver path can be adjusted and calibrated according to a response of the receiver path.Type: GrantFiled: June 5, 2014Date of Patent: November 29, 2016Assignee: MStar Semiconductor, Inc.Inventors: Ming-Yu Hsieh, Po-Yang Chang, Tzu-Chin Lin, Yi Lu
