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 k/spl Omega/ 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 dB/spl Omega/, and an equivalent input noise current density of 12 pA//spl radic/(Hz), using 35-GHz Si bipolar technology.

用于10gb /s光纤链路的宽动态范围1k /spl ω /透阻Si双极前置放大器IC

介绍了一种用于10gb /s光纤链路的宽动态范围、高跨阻硅双极前置放大器集成电路。为了克服高跨阻和宽动态范围之间的权衡，在跨阻级之后引入了限制放大器。采用35 GHz Si双极技术，在10.5 GHz带宽下实现了1 k/spl Omega/的高跨阻和高达2 mApp的宽输入电流动态范围，低跨阻波动为0.5 dB/spl Omega/，等效输入噪声电流密度为12 pA//spl radig /(Hz)。
