Patent number: 12250002Abstract: A SAR ADC includes: a sample-hold (S/H) circuit sampling an input voltage to generate a S/H output signal; a DAC generating a DAC output signal; a comparator comparing the DAC output signal with the S/H output signal to generate a comparison output signal; a SAR combinational digital circuit group; a multiplexer circuit; and a plurality of registers for registering the comparison output signal as register output signals and outputting as an output signal of the SAR ADC. The SAR combinational digital circuit group generates a plurality of first and second SAR output signals based on the register output signals. The multiplexer circuit is controlled by on the register output signals to select among the first and the second SAR output signals as a plurality of multiplexer output signals for sending to the DAC. A capacitor coupling relationship of the DAC is controlled by the multiplexer output signals.Type: GrantFiled: March 28, 2023Date of Patent: March 11, 2025Assignee: UNITED MICROELECTRONICS CORP.Inventors: Po-Hua Chen, Yu-Yee Liow, Chih-Wei Wu, Wen-Hong Hsu, Hsuan-Chih Yeh, Pei-Wen Sun

Publication number: 20240297482Abstract: A laser module includes a substrate, a laser unit, an optical amplification unit, a high reflection layer and a low reflection layer. The laser unit is disposed on the substrate and configured to generate a laser light. The optical amplification unit is disposed on the substrate. An optical channel of the optical amplification unit is communicated with an optical channel of the laser unit. An electrode of the optical amplification unit is electrically isolated from an electrode of the laser unit. The high reflection layer is disposed on an end of the laser unit away from the optical amplification unit. The low reflection layer is disposed on an end of the optical amplification unit away from the laser unit. The laser light and a gain light are emitted to an outside of the laser module via the low reflection layer. A method for manufacturing the laser module is also provided.Type: ApplicationFiled: December 7, 2023Publication date: September 5, 2024Inventors: PO-HONG CHEN, YI-JEN CHIU, KUAN-YU CHEN, CHUNG-WEI HSIAO

Patent number: 8410337Abstract: An isolated polypeptide containing an amino acid sequence at least 70% identical to a Tubby-like protein (SEQ ID NO: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11), and an isolated nucleic acid encoding the polypeptide. Disclosed is an isolated nucleic acid that, under stringent conditions, hybridizes to a probe containing one of SEQ ID NOs:1-11; or its complementary sequence. Also disclosed are (1) a transformed cell or a transgenic plant containing such a nucleic acid and (2) a transformed cell or a transgenic plant having a reduced level(s) of one or more of the Tubby-like proteins. Also within the scope of the invention are methods for making the transformed cells or transgenic plants.Type: GrantFiled: February 17, 2009Date of Patent: April 2, 2013Assignee: Academia SinicaInventors: Jei-Fu Shaw, Chia-ping Lai, Po-Hong Chen
