Abstract
A wide dynamic range and high transimpedance Si bipolar preamplifier IC for 10-Gb/s optical fiber links is described. A limiting amplifier was introduced after the transimpedance stage to overcome the trade-off between high transimpedance and a wide dynamic range. A high transimpedance of 1 kΩ and a wide input current dynamic range up to 2 mApp were achieved with a bandwidth of 10.5 GHz, a low transimpedance fluctuation of 0.5 dBΩ, and an equivalent input noise current density of 12 pA/√Hz, using 35-GHz Si bipolar technology.
