Abstract

An optical receiver analog front-end circuit is implemented in SMIC 0.18um Mixed-signal process. The circuit provided an overall gain of 85dB with a bandwidth of 4.36 GHz while drawing 150mW from a 1.8 V supply. A 2.5 V supply is used which only offers a voltage potential. The chip area is only 1.0"0.7mm2, including the pads. Some improvements aiming at boosting the circuit performance are also presented. [ABSTRACT FROM AUTHOR]

Abstract

A 5Gb/s optical receiver front-end for optical interconnection is presented in this paper. A transimpedance amplifier (TIA), limiting amplifiers (LA), output buffer and a bias circuit are integrated in deep Nwell 0.18μm CMOS technology. As the input current amplitude is 30μA, the differential output voltage is achieved to be 124 mV. The linear gain is 78.8dBΩ and consumes 200mW under 1.8V supply. Without on-chip inductor, the core size of the circuit is only 800×300μm2. [ABSTRACT FROM AUTHOR]
