Publication number: 20220310511Abstract: Semiconductor devices and methods of formation are provided herein. A semiconductor device includes a first inductor, a patterned ground shielding (PGS) proximate the first inductor comprising one or more portions and a first switch configured to couple a first portion of the PGS to a second portion of the PGS. The semiconductor device also has a configuration including a first inductor on a first side of the PGS, a second inductor on a second side of the PGS and a first switch configured to couple a first portion of the PGS to a second portion of the PGS. Selective coupling of portions of the PGS by activating or deactivating switches alters the behavior of the first inductor, or the behavior and interaction between the first inductor and the second inductor. A mechanism is thus provided for selectively configuring a PGS to control inductive or other properties of a circuit.Type: ApplicationFiled: June 6, 2022Publication date: September 29, 2022Inventors: Hsiao-Tsung YEN, Chin-Wei KUO, Cheng-Wei LUO, Kung-Hao LIANG

Patent number: 8709720Abstract: Disclosed herein is a method for identifying single nucleotide polymorphisms of a target nucleic acid for predicting whether a patient suffering from hepatocellular carcinoma will respond to a 5-fluorouracil (5-FU)-based combination chemotherapy. In some embodiments, biological sample derived from the patient is processed to determine the presence of a T/T genotype of rs9679162 GALNT14 gene. The presence of the above-identified genotype is an indication that the patient is responsive to the 5-FU-based combination chemotherapy.Type: GrantFiled: March 2, 2012Date of Patent: April 29, 2014Inventors: Chau-Ting Yeh, Kung-Hao Liang

Publication number: 20090174460Abstract: A third-order transconductance (gm3) cancellation is utilized to obtain a highly linear mixer. Transistors obtain good linearity with complementary gm3 values. The transistor thus obtained can be operated in a wide bandwidth and is applicable to various frequency specifications of systems, like Bluetooth, wireless LAN, Ultra-Wide Band (UWB), etc. Then the transistors are applied to design a transconductance-stage input of the mixer. Hence, the present invention can be widely applied to receiver modules and be realized with a low-cost CMOS transistor.Type: ApplicationFiled: March 21, 2008Publication date: July 9, 2009Applicant: National Central UniversityInventors: Yi-Jen Chan, Kung-Hao Liang, Hong-Yeh Chang
