This paper presents a 26-Gb/s CMOS optical receiver that is fabricated in 65-nm technology. It consists of a triple-inductive transimpedance amplifier (TIA), direct current (DC) offset cancellation circuits, 3-stage gm-TIA variable-gain amplifiers (VGA), and a reference-less clock and data recovery (CDR) circuit with built-in equalization technique. The TIA/VGA front-end measurement results demonstrate 72-dB Omega transimpedance gain, 20.4-GHz -3-dB bandwidth, and 12-dB DC gain tuning range. The measurements of the VGA's resistive networks also demonstrate its efficient capability of overcoming the voltage and temperature variations. The CDR adopts a full-rate topology with 12-dB imbedded equalization tuning range. Optical measurements of this chipset achieve a 10(-12) BER at 26 Gb/s for a 2(15) -1 PRBS input with a -7.3-dBm input sensitivity. The measurement results with a 10-dB @ 13 GHz attenuator also demonstrate the effectiveness of the gain tuning capability and the built-in equalization. The entire system consumes 140 mW from a 1/1.2-V supply.
