摘要： A voltage-mode line driving circuit is provided. The voltage-mode line driving circuit includes a driving circuit, the driving circuit receiving, as an input signal, a feedback signal, and outputting an output signal. The voltage-mode line driving signal also includes an adaptive tuning circuit coupled to the driving circuit, the adaptive tuning circuit receiving as input signals the feedback signal and the output signal and adaptively outputting a modifying signal to the driving circuit which modifies the feedback signal.

摘要： The methods and systems presented herein provide an improved means of correcting the variation of Voltage Output Differential (VOD) in differential drivers. In some embodiments, a high-precision reference voltage is generated not only based on a desired VOD, but also by monitoring the Voltage Common Mode (VCM) in a differential driver. In some embodiments, the VOD is then compared with the high-precision reference voltage to correct the output current. The result is a low-variation output voltage.

摘要： An input termination circuit includes a first and a second resistor each having a terminal respectively coupled to a first and a second input terminal of the input termination circuit, a first and a second transistor coupled in series between the first resistor and the second resistor, and a third transistor having two terminals respectively coupled to the control circuit and a node between the first and the second transistor. The gate of the third transistor is coupled to ground. The gates of the first and the second transistor are coupled to a control circuit that is adapted to provide a control signal to turn the first and the second transistor on or off.
