A 10Gb/s CMOS AGC Amplifier with 35dB Dynamic Range for 10Gb Ethernet

A 10Gb/s AGC amplifier is implemented in 0.18μm CMOS technology. The circuit uses a linear-in-dB controlled VGA with 58dB tuning range. For input swings from 18mV pp to 1V pp , the output swing is 430mV pp within +0.4 to -0.8dB variations. The measured dynamic range is 35dB with BER
