A 10Gbps Limiting Amplifier for STM-64 Application Driver in 0.18μm CMOS Technology

Abstract:

An inductorless circuit for limiting amplifiers is present. With the third-order interleaving active feedback, the bandwidth of this circuit could be enhanced while keeping a suppressed gain. The amplifier is simulation in a 0.18μm CMOS technology. The results show that the circuit consuming a DC power of 90mW with a 1.8V supply voltage, its voltage gain is about 42.6dB, the 3dB bandwidth of the circuit is 10.96GHz.The limiting amplifier circuit can be used in the STM-64 optical fiber communication system.
