Design of an optical amplifier with increasing bandwidth of dynamic range for optical receiver applications

In this paper an optical amplifier with increased dynamic range bandwidth with inductive amplification technique, including a transient impedance amplifier (TIA) for use in an optical telecommunication system for applications with 10Gb / s data rate using CMOS18.0.0 µm technology Designed and simulated. For the proper design of a fiber optic amplifier, the design of the transient impedance amplifier is a key element of this type of amplifier so that it compromises between challenging issues such as bandwidth, gain and power consumption. Appropriate bandwidth and interest required for use in new telecommunications And transfer an image. In this paper, the inductive enhancement technique developed by the predecessor is used to improve the parameters. In this technique, the desired inductor resonates with the parasitic capacitors of the circuit and creates a peak in the circuit which increases the bandwidth and gain of the circuit. Linear Mode In certain situations, such as short-circuit optical fiber, a technique called shunt technique is used to keep the circuit in linear mode. . The simulation results show that the proposed circuit has 1.8v power supply, 57.6 mW power, 5.98GHz bandwidth and 25dBΩ output.
