Abstract :
This work introduces a monolithic 10GBase-LX4 limiting amplifier in a low-cost 0.18 mum CMOS digital process intended for optical fiber communications. The proposed configuration includes two inductorless frequency compensated voltage amplifiers. The topology also incorporates a conventional RC network in order to avoid drifts due to matching and temperature between -20 and 80degC. This circuit presents a 200 kHz lower cut-off frequency and a 3.5 GHz higher cut-off frequency with 32 dB gain.
