N2 - A novel inverter-based transimpedance amplifier (TIA) employing shunt-shunt inductive feedback and input series peaking is implemented in 65-nm CMOS for 100Gbit Ethernet (100GbE) receivers. The multiple peaking scheme provides an overall bandwidth enhancement ratio of 2.8 to deliver 42-dBQ of gain up to 24 GHz. To suppress the wideband noise from the TIA power supply and to alleviate the loading effect due to the supply bond-wires, a low-dropout regulator (LDO) with full-spectrum power supply rejection (PSR) of at least -12 dB is co-designed and integrated with the TIA. Measurements at 25 Gb/s show that the data eye RMS and peak-to-peak (P-P) jitters are improved by 15% and 24%, respectively, with the LDO enabled. The measured TIA sensitivity is -7.3 dBm at 25 Gb/s with a BER < 10'12 for a 215-1 PRBS optical input. The TIA with LDO consumes 3 mW from a 1.2-V supply.
