【摘要】 文中报告了作者研制的QD-3181型线性电路电压噪声测试仪,给出了对几种高精度线性集成电路低频电压噪声密度的测量结果和比较。在10Hz、100Hz、1kHz三点频下,测得作者研制的超β器件的低频电压噪声密度分别为4.0nV/（Hz）^1/2、2.0nV/（Hz）（1/2）和1.5nV/（Hz）^1/2。更多还原

【Abstract】 QD-3182 linear circurt voltage noise test instrument has been developed. Several measured results for low frequency voltage noise density in high precision linear integrated circuit are given and compared with each other. The voltage noise densities in our super-β device measured at 10Hz, 100 Hz and 1kHz are 4.0nV/Hz,2.0nV/Hz and 1.5nV/Hz respectively.更多还原
