Abstract


Communications technology industry , the rapid development of the increasing amount of information exchange . Optical fiber communication frequency bandwidth , large capacity , low loss , anti-radiation, anti- corrosion and is rich in resources , and many other advantages of a high-speed communications systems research hotspot . Key optical receiver module as an important part of the optical fiber communication systems , limiting amplifier performance has a direct impact on the performance of the optical receiver and even fiber optic system . Design a limiting amplifier having high performance of the entire optical fiber communication system has a very important significance . The subject based CHARTERED 0.35μm CMOS technology for optical fiber communication systems STM-1 (155Mbps) rate level compatible with 3.3V and 5V supply voltage to meet the practical application of the requirements of the limiting amplifier chip . Limiting amplifier selection multistage cascade of fully differential structure effectively suppress common mode noise , and without increasing extra chip area and power under the premise of effectively expand the bandwidth fT doubler and insert the source follower . Meanwhile, the design of a DC offset compensation circuit , effectively compensate for the mismatch due to the manufacturing process and layout . In addition, according to the practical application , to avoid wasting power consumption within the chip also integrates the loss of signal detection circuit of the threshold value is programmable , to effectively control the output buffer circuit according to the size of the input signal amplitude to ensure normal data processing circuit in the subsequent clock recovery job. The final completion of the layout of the limiting amplifier , the overall layout of the chip area of only 1.2 × 1.2mm2 ( 12 ESD 12 PAD) . And extracted layout netlist with parasitic parameters using Hspice post-simulation after simulation results show that the limiting amplifier designed in this paper in the supply voltage of 3.3V IF gain of 49.8dB , -3dB bandwidth of 194.5MHz static power consumption is only 82mW, maintain 980mV stable output from 18mVpp to the 1.8Vpp the input dynamic range , and has a good eye diagram output to meet the optical fiber communication in the most basic and important STM - 1 ( 155Mbps ) rate standard applications require to meet chip high-performance requirements .
