Based on the equivalent circuit model of a two-port optical receiver front-end, the relationship between the equivalent input noise current spectral density and the noise figure is analyzed.
根据光接收机前端等效电路模型,建立了噪声系数与等效输入噪声电流谱密度的关系。
With this shield in place, the noise current generated by the electrostatic voltage source and the coupling capacitance flows through the shield to ground rather than through the signal conductors.
有了这种屏蔽,由静电电压源和耦合电容产生的噪声电流就经过屏蔽流到地,而不再流过信号线。
