摘要: A pre-driver circuit includes a first stage to generate a first pre-driver signal and a second stage to generate a second pre-driver signal. The first and second stages are to generate the first and second pre-driver signals to cross at a point which reduces rise-and-fall mismatch in differential signal outputs from a current-mode driver.

摘要: In one embodiment, the present invention includes a method for associating a first plurality of current sources with a first tap coefficient and associating a second plurality of current sources with a second tap coefficient. A first plurality of output switches coupled to the first plurality of current sources is gated using the first tap coefficient and a second plurality of output switches coupled to the second plurality of current sources is gated using the second tap coefficient. In such manner, the first and second plurality of equalized current sources may be driven onto an interconnect. Other embodiments are described and claimed.

摘要: In general, in one aspect, the disclosure describes an apparatus having an averager to receive differential output voltages of a transmitter and generate an average transmitter output voltage. A comparator is to compare the average transmitter output voltage to a reference voltage and generate a difference therebetween. An integrator is to integrate the difference between the average transmitter output voltage and the reference voltage over time. The integrated difference is fed back to the transmitter to bias the transmitter.
