High-Performance CMOS and BiCMOS Transimpedance Preamplifiers for Optical Communications
نویسنده
چکیده
High-performance transimpedance preamplifiers (TIAs) based on new CMOS common-gate (CG) and BiCMOS common-base (CB) schemes have been designed for optical communications. The new design approach potentially allows the efficient employment of circuit techniques to optimize performance tradeoffs inherent in such circuits. Using conventional silicon 0.8μm process parameters, simulated performance features of 3.7 GHz CMOS-CG and 7.5 GHz BiCMOS-CB TIAs are presented. The results are superior when compared to those of similar recent designs. The new design approaches IC designs using GaAs or InP technologies.

Integrated Wideband Low-Noise Current-Mode Transimpedance Preamplifiers for Optical Receivers
Classic designs of optical transimpedance amplifiers for p-i-n photodiode receiver circuits generally employ common-emitter or common-source input stages. In this paper, we explore the design of a new calss of highperformance "current-mode" optical transimpedance preamplifiers based on CMOS and BiCMOS common-gate and common-base input stages using a new-design approach hereafter called “total-t...

In this paper, we present a CMOS preamplifier for use with magnetoresistive (MR) read elements in disk drives. The performance of the CMOS design is competitive with the more expensive current generation of BiCMOS MR preamplifiers. The measured gain for the preamplifier is 43 dB and the measured 3-dB bandwidth is greater than 273 MHz corresponding to a 455-Mb/s data rate. Likewise, the measured...

متن کاملA CMOS Optical Preamplifier for Wireless Infrared Communications
This paper describes a CMOS optical preamplifier suitable for infrared wireless data communications. The preamplifier consists of a differential CMOS variable-gain transimpedance amplifier embedded in a larger feedback loop used to reject photocurrents generated by ambient light. Fabricated in a commercial 0.35m CMOS process, the preamplifier consumes 8 mW at 3 V, and provides 70-MHz bandwidth ...
