Linear Analog Front -End Circuits for Fiber -Optic Communication Systems

Second, a variable gain amplifier is designed for electronic dispersion compensation based 10-Gb/s optical links. The design incorporates tunable emitter degeneration, hence satisfying linearity, bandwidth, and supply voltage requirements. Also, an analog multiplexer provides a wide gain tunability and enhanced linearity. The VGA achieves tunable gain from 2.43 dB to 44.37 dB while being process insensitive; a worst case spurious free dynamic range of 26.46 dB with an output swing of 1.4 Vpp, and minimum 3-dB bandwidth of 6.5 GHz consumes 102 mW of power in a 3.3-V, 0.25-mum SiGe BiCMOS process.
