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.
