| 英文摘要 | A pulse amplitude modulation (PAM) signal generator is disclosed. The PAM signal generator, which is applicable to a vertical cavity surface emitting laser diode (VCSEL), provides a plurality of differential units each having two outputs complementary to each other and biased by a power supply voltage through the commonly connected VCSEL and a dummy diode. The differential units have respective current sources each, where partial sums and a total sum of the currents correspond to the multiple output levels of the VCSEL. The PAM signal generator also provides compensating units to compensate the saturation (non-linearity) of the optical output of the VCSEL. |
