Patent number: 10644911Abstract: A multi-level pulse-amplitude modulation receiver system includes an analog equalizer, a digital equalizer, an automatic level tracking engine and an automatic gain controller. The analog equalizer and the automatic gain controller perform signal compensation on a multi-bit quasi-attenuation signal to generate a multi-level compensation signal. The digital equalizer receives the multi-level compensation signal, the positive threshold voltage and the negative threshold voltage, and thereby converts the multi-level compensation signal into a plurality of digital data. The automatic level tracking engine uses the digital data to generate a positive threshold voltage, a negative threshold voltage, at least two positive DC level voltages, and at least two negative DC level voltages, and the positive threshold voltage is an average of the two positive DC level voltages to avoid the nonlinear effect of the analog front end.Type: GrantFiled: August 22, 2019Date of Patent: May 5, 2020Assignee: National Chiao Tung UniversityInventors: Wei-Zen Chen, Chia-Tse Hung, Yu-Ping Huang, Yao-Chia Liu

Patent number: 6586146Abstract: A method of figuring an exposure energy. A required exposure energy is calculated according to a critical dimension (CD) of an exposing layer. A first CD deviation is obtained from a layer before the exposing layer. From the first CD deviation, a first energy compensation is calculated. Whether the deviation of photoresist sensitivity of two sequential batches is less than 1% is checked. If the deviation of photoresist sensitivity of two sequential batches is less than 1%, a sum of the required exposure energy and the first energy compensation is the exposure energy applied to the exposing layer. Otherwise, a second CD deviation is commutated according to the deviation of photoresist sensitivity of two sequential batches. A second energy compensation is then obtained from the second CD deviation, and a sum of the required exposure energy and the first/second energy compensation is the exposure energy applied to the exposing layer.Type: GrantFiled: August 31, 2001Date of Patent: July 1, 2003Assignee: United MicroelectronicsInventors: Kun-Yuan Chang, Wang-Hsiang Ho, Yu-Ping Huang, Li-Dar Tsai, Chung-Yung Wu
