Abstract
This paper presents a fully-integrated optical receiver in 28nm bulk CMOS for 1310 and 1550nm light, suitable for single-mode fiber communication. The fill factor of the Schottky photodiodes is maximized and the transimpedance amplifier is based of a voltage amplifier with high gain. This technique reduces the input-referred noise current for a given bandwidth. The receiver has a core area of 145x185µm2, while consuming 42mW. The circuit achieves data rates up to 3Gb/s at a BER of 3e-8 and a sensitivity of 0.1dBm for 1310nm light, and up to 1Gb/s at a BER of 4.8e-9 and sensitivity of 0.5dBm for 1550nm light.
