Co-design of a differential transimpedance amplifier and balanced photodetector for a sub-pJ/bit silicon photonics receiver
Co-design of a differential transimpedance amplifier and balanced photodetector for a sub-pJ/bit silicon photonics receiver
This paper presents the design and implementation of a fully differential optical receiver, which is aimed for short reach intensity modulation and direct detection (IMDD) transceiver links. A Si-Ge balanced photodetector (PD) has been co-designed and packaged with a novel differential transimpedance amplifier (TIA). The TIA design is realized with a standard 28nm CMOS process and operates with a standard digital supply (1V). Without using any equalization or DSP techniques, the proposed receiver can operate up to 54Gb/s with a BER less than the KP4 limit (2.2×10-4) under an optical modulation amplitude (OMA) of -8.6dBm, while the power efficiency has been optimized to 0.55pJ/bit (0.98pJ/bit if output buffer is included).

Abstract
This paper presents the design and implementation of a fully differential optical receiver, which is aimed for short reach intensity modulation and direct detection (IMDD) transceiver links. A Si-Ge balanced photodetector (PD) has been co-designed and packaged with a novel differential transimpedance amplifier (TIA). The TIA design is realized with a standard 28nm CMOS process and operates with a standard digital supply (1V). Without using any equalization or DSP techniques, the proposed receiver can operate up to 54Gb/s with a BER less than the KP4 limit (2.2×10-4) under an optical modulation amplitude (OMA) of -8.6dBm, while the power efficiency has been optimized to 0.55pJ/bit (0.98pJ/bit if output buffer is included).
