A front-end optical receiver in 0.6 μm BiCMOS technology is introduced to maintain equally spaced levels and constant output signal swing for multilevel signals at different input optical powers. The symbol error rate measurements for 4-PAM signals show a better sensitivity than with a conventional optical receiver. It is believed that this is the first time that complete performance characteristics for an optical receiver front-end designed especially for multilevel data transmission have been reported.
