Patent number: 10734958Abstract: A line receiver is described. The line receiver may be configured to receive signals transmitted via a communication channel, such as a metal trace on a printed circuit board or a cable. The receiver may comprise a buffer and circuitry for enhancing the trans-conductance gain of the buffer. By enhancing the trans-conductance gain of the buffer, linearity may be improved and susceptibility to process and temperature variations may be limited. Enhancement of the trans-conductance gain may be performed using feedback circuitry coupled to the buffer. The receiver may further comprise mirror circuitry configured to provide a desired current to the load. The receiver may further comprise a gain stage for setting the gain of the receiver to a desired level.Type: GrantFiled: February 15, 2017Date of Patent: August 4, 2020Assignee: MediaTek Inc.Inventors: Ramy Awad, Tamer Ali
