Genetic-algorithm Optimization of Dipole Equivalent-circuit Models
چکیده
A novel topology of single-input to differential-output converters suitable for designing differential output transimpedance amplifiers has been proposed. The converter provides 6 dB extra gain with respect to a simple differential pair, and allows us to design transimpedance amplifiers featuring improved performance in terms of conversion gain, input impedance, and offset compensation with respect to commonly used transimpedance topologies. A front-end amplifier for SDH systems operating at 10 Gbit s has been designed and fabricated in Philips PML Ž . ED02AH GaAs HEMT technology 0.2 m gate length .
