Described is an apparatus which comprises: a first capacitor coupled to a first input pad; a second capacitor coupled to second input pad; a first resistor coupled to the second capacitor; a third capacitor coupled in series with the first resistor; a second resistor coupled in series with the third capacitor and also coupled to the first capacitor; and a differential amplifier coupled to the first and second capacitors and to the first and second resistors.

Method and apparatus for passive continuous-time linear equalization with continuous-time baseline wander correction

Described is an apparatus which comprises: a first power supply; a second power supply lower than the first power supply; first and second transistors coupled in series and to be biased, the first and second transistors coupled to a pad; a first pull-up transistor coupled to the first power supply and to one of the first or second transistors; a pull-down transistor coupled to one of the first or second transistors; and a second pull-up transistor coupled to the second power supply, the pull-down transistor, and to one of the first or second transistors.

Apparatus for high voltage tolerant driver

Described is an apparatus which comprises: an amplifier; and a passive continuous-time linear equalizer integrated with a baseline wander (BLW) corrector, wherein the integrated equalizer and BLW corrector is coupled to the amplifier.

Techniques for embedded high speed serial interface methods are described herein. The techniques provide an apparatus for link equalization including an equalization control module to determine at least a first coefficient setting and a second coefficient setting at a remote transmitter based on an algorithm. The apparatus also includes a receiver margining module to determine a first margin value to be associated with the first coefficient setting and a second margin value to be associated with the second coefficient setting. The receiver margining module is to further determine if at least the first margin value is higher than the second margin value.

Link equalization mechanism

Predriver equalization is described. A predriver includes a predriver equalizer to provide equalization on outputs of predrivers. The predriver equalization causes the predrivers to drive the output driver and a preemphasis driver with signals equalized to reduce common mode noise on the output signal. The predrivers can be implemented as complementary semi-differential driver circuits or as complementary logic circuits with weak pull-downs. The driver complexity can be reduced to the use of a semi-differential driver with the use of the predriver equalization.

Predriver equalization for common mode noise reduction in a semi-differential current mode driver

An on-die voltage regulator having a suspend mode voltage generator and an active mode voltage generator. Output drivers of the active mode voltage generator are disabled in stages to reduce voltage droop when transitioning between the active mode voltage generator and the suspend mode voltage generator.
