A high-speed, low-noise transimpedance amplifier has been implemented in 0.8 μm digital CMOS technology. Featuring a broadband input source-follower stage, the amplifier has an effective transimpedance gain of 66.5 dBΩ (2110 Ω), consuming 155 mW. The measured input noise current density of the amplifier is 4.6 pA/√Hz. With equivalent input sensitivity of -24 dBm at 1 Gbit/s for 10-12 bit error rate (BER). To the authors knowledge, this is the first gigabit transimpedance amplifier ever demonstrated in standard CMOS technology
