Patent number: 7583752Abstract: A differential signal transmitter including a driver circuit that generates a differential signal in response to data input. The amplitude of the voltage swings in the differential circuit is controlled by an electrical bias. Two data inputs, one being the original Data and the other being Data bar, are connected to the transistors and cause the required signal swings. The transmitter further includes a control circuit with an input for a single-bit control line for adjusting the bias to produce different swing amplitudes according to a control indicator inputted from the control line. The control circuit inputs one or more current sources and outputs the sum of one or more of the current sources according to the control indicator and the outputted current is used as the electrical bias.Type: GrantFiled: November 13, 2006Date of Patent: September 1, 2009Assignee: Faraday Technology Corp.Inventors: Kuei-Chun Teng, Shin-Lin Wang

Patent number: 6777983Abstract: A differential voltage transmission circuit. The reference bias circuit outputs a first reference voltage, a second reference voltage and a reference current corresponding to a reference current adjusting signal. The differential comparator compares the difference between the first reference voltage and the second reference voltage with the difference between a first output voltage and a second output voltage, and outputs a result signal corresponding to the compared result. The decision circuit outputs the reference current adjusting signal corresponding to the result signal. The output circuit outputs the first output voltage and the second output voltage generated at both terminals of a termination resistor when the reference current flows through the termination resistor.Type: GrantFiled: May 22, 2003Date of Patent: August 17, 2004Assignee: Faraday Technology Corp.Inventors: Shin-Lin Wang, Kun-Chih Chang
