对于高速光通信应用，光电探测器的带宽将是一个关键的限制。在我们提出的不同指宽的串联和增强型增益峰值光电探测器电路的基础上，研究了考虑RC和渡越限制的MgZnO基金属-半导体-金属（MSM）光电探测器的带宽特性。为了保证参数的准确性，采用三谷系综Monte Carlo模拟结合第一性原理计算，研究了MgZnO的高场输运特性.结果表明，增益峰化技术，尤其是增强增益峰化技术，可以使MgZnO MSM光电探测器的带宽最大提高到61.28 GHz，相应的带宽提高了49%，而没有任何不良影响。进一步进行了三维电磁场计算，对片上电感进行了设计和仿真。模拟电感的值约为0.0529 nH，即...
For high-speed optical communication applications, the bandwidth of photodetector would be a key limitation. In this work, the bandwidth property of MgZnO-based Metal-Semiconductor-Metal (MSM) photodetector considering RC and transit limitations is investigated on the basis of the series and enhanced gain peaked photodetector circuits proposed by us with different finger widths. To ensure the accuracy of parameters, the high-filed transportation characteristics of MgZnO are investigated by a three-valley ensemble Monte Carlo simulation combined with first principle calculations. The results show that the gain peaking technique, especially the enhanced gain peaking, can improve the bandwidth of MgZnO MSM photodetector to a maximum value of 61.28 GHz, corresponding to a bandwidth enhancement of 49% without undesired effects. Three-dimensional electromagnetic computation is further performed to design and simulate the on-chip-inductor. The value of the simulated inductor is approximately 0.0529 nH, which is ...
