Abstract

In this paper, a high-gain, noise-optimized bandpass-like transimpedance amplifier (TIA) chip is presented. The TIA chip is implemented in a 130 nm SiGe BiCMOS technology and consists of a 2nd order high-pass filter (HPF), shunt-feedback TIA stage, Gilbert cell based variable gain amplifier (VGA) having an ac-coupled Cherry-Hooper load circuitry allowing for low supply voltage and finally a cascode based output buffer. The TIA chip is optimized for operation with a commercial photodetector (PD) in a quasi-coherent optical receiver. The experimental results of the fabricated TIA chip shows a 7-30 GHz bandwidth and differential transimpedance of 80-dBΩ. An evaluation board containing the TIA chip is employed in a 10 Gbps transmission experiment and a state-of-the-art sensitivity for quasi-coherent receivers is achieved.
