Abstract :
Equalizing amplifier circuits for a gigabit optical fiber transmission system are integrated on two monolithic chips incrementing an advanced silicon bipolar process. Several new circuit techniques such as a broad band 50 ohm matching amplifier and an electrically controlled and adjusted peaking technique are employed. The gain and maximum 3-dB down bandwidth are 64 dB and 1.2 GHz, respectively. The noise figure obtained is 4.5 dB within the DC to 2 GHz range.
