Abstract
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.
Claims27
A circuit, comprising:
- a first stage to generate a first pre-driver signal;
- and
- a second stage to generate a second pre-driver signal,
- wherein 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.

A method for controlling a current-mode driver, comprising:
- generating a first pre-driver signal to control a steering transistor in the driver;
- and
- generating a second pre-driver signal to control a complementary steering transistor in the driver, wherein the first and second pre-driver signals cross at a point which reduces mismatch in rise and fall transitions of a differential driver signal output.
A system, comprising:
- a first circuit;
- and
- a second circuit including:
- (a) a first stage to generate a first pre-driver signal, and
- (b) a second stage to generate a second pre-driver signal, wherein the first and second pre-driver signals cross at a point which reduces rise-and-fall mismatch in a differential signal output from a current-mode driver.
