A laser driver circuit for reducing electromagnetic interference is
disclosed. The laser driver circuit includes a first differential
amplifier circuit, a second differential amplifier circuit and a glitch
smoothing circuit. The first differential amplifier circuit is coupled to
a pair of differential input signals, and is configured to generate a
first amplified signal. The second differential amplifier circuit is
coupled to the pair of differential input signals, and is configured to
generate a second amplified signal. The first and second amplified
signals together form a differential pair of output signals. The glitch
smoothing circuit has a first output terminal coupled to the first
differential amplifier circuit and a second output terminal coupled to
the second differential amplifier circuit. The glitch smoothing circuit
is configured to reduce glitches on the differential pair of output
signals when the pair of differential input signals switch states.
