A CMOS Low-Noise and Low-Power Transimpedance Amplifier

For specified applications of 2.5 Giga-bit-per-second, a low-noise and low-power transimpedance amplifier (TIA) is introduced here. The introduced TIA possess an active feed-forward network based on current-mirror structires beside an active load, that resonates with the capacitive load. Using 90nm CMOS library parameters, the presented TIA prvides -3dB frequency of 1.7GHz and 54.53dB ohm gain, with consumpting power of 2mW, and producing 12.6pA/√Hz input referred noise.
