If the short circuit has a very low thermoelectric EMF, this can be used to verify inputnoise and zero drift with time.
如果输入端的短路点具有很低的热电动势,用这种方法就可以验证输入噪声和零点随时间的漂移。

As the charge exerted from input voltage source is dependent on quantization error and inputnoise voltage to a large extent, the circuit has high signal input impedance.
由于提取自输入电压源的电荷很大程度上仅取决于量化误差与输入噪声电压,所以电路具有高信号输入阻抗。

Based on the equivalent circuit model of a two-port optical receiver front-end, the relationship between the equivalent inputnoise current spectral density and the noise figure is analyzed.
