Efficient synthesis methodology for optimal inverter-based transimpedance amplifiers


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.
