介绍了一种用于光互连的低噪声高速跨阻放大器。对于光接收机的高密度并行集成，除了高速、低功耗等要求外，小面积和串扰抑制也是非常重要的。提出了一种具有无电感带宽补偿电路和无源串扰滤波器的逆变器TIA(INV-TIA)。由于这些附加电路是由电阻和电容组成的，因此面积开销和功率开销比现有技术小得多。我们在65 nm的CMOS片上制作了25 GB/S的TIA。与参考电路相比，输入参考噪声降低了60%，串扰噪声降低了25%。
This paper presents a low-noise and high-speed transimpedance amplifier (TIA) for optical interconnection. For high density parallel integration of optical receiver, small area and crosstalk mitigation arc important as well as high speed, low power and so on. We propose an inverter TIA (INV-TIA) with inductor-less bandwidth compensation circuits and a passive crosstalk filter. Since these additional circuits are composed with resistance and capacitance, the area overhead and the power overhead are much smaller than existing techniques. We fabricated a 25 Gb/s TIA in a 65-nm CMOS. Compared to the reference design, the proposed circuit reduces the input referred noise by 60% and the crosstalk noise by 25%.
