ABSTRACT: In this paper, we present a new synthesis methodology that facilitates the design automation of maximum bandwidth transimpedance
amplifier (TIA) for optical communications under the constraint of a specific bit error rate. Our synthesis methodology is
based on newly developed models that characterize the input referred noise and bandwidth. Our technique provides the optimal
parameters of the transimpedance amplifier for maximizing the bandwidth. These optimal parameters are mapped to equivalent
circuit parameters to achieve the optimal sizing of the TIA. Our methodology is characterized by its very fast design convergence
as well as better results compared to conventional design techniques. We applied our synthesis methodology in designing a
TIA for optical interconnect systems using the 0.25μm and 0.18μm CMOS technologies.
