In this chapter, we will introduce the basic concept of a high-speed receiver, the integrated circuit (IC) technique of the front-end. Subsequently, passive peaking techniques for a preamplifier are described.
In optical receivers, achieving a low-noise front-end amplifier while maintaining bandwidth is a challenge. This challenge arises due to the trade-off between bandwidth and noise. This paper proposes a
The optical front end (OFE) is a critical part in most Optical Wireless Communica-tion (OWC) systems. It captures the incoming light flux, converts it and amplifies it into an electrical signal.
This thesis investigates two different implementations of optical receiver front- end circuits with photodetectors to take advantage of the unique properties of inexpensive mature CMOS
A 56-Gb/s PAM-4 optical receiver front-end circuit implemented in a 40-nm CMOS process has been presented in this paper. The proposed design integrates a TIA, VGA, output buffer, DCOC circuit,
This thesis is focused on optical receiver front-ends. This section will discuss the impact of integrated circuit technology and modulation scheme on the design of optical receiver front-ends while providing
This paper presents an optimized design methodology for an inductor-less 28-Gb/s NRZ optical receiver (ORx) analog front-end (AFE) using the Berkeley Analog Generator (BAG) in 28-nm
This reference design describes a complete end-to-end optical front-end system and its performance. Various techniques to optimize the SNR performance of the signal chain are also discussed.
Abstract: This paper presents design of front end optical receiver using CMOS 180nm technology. After completion of its schematic view, simulation is done through Cadence Virtuoso tool.
