low-level amplifier

基本解释

We identified a synaptic amplifier at the origin of an ascending pain pathway that is switched-on by low-level activity in nociceptive nerve fibers.
研究人员说，突触的变化放大了疼痛信号，潜在地增加了一个人对疼痛的敏感性。
A low reset noise CMOS image sensor (CIS) based on column-level feedback reset is proposed. A feedback loop was formed through an amplifier and a switch.
提出了一种通过放大器和开关建立起反馈环路，基于列级反馈复位的低噪声CMOS图像传感器（CIS）。

In order to reduce the output noise to the relative low level, the LDO is employed. As the heart of the LDO, the operational amplifier, band-gap reference and bypass PMOSFET are all introduced.
阐述了电荷泵的工作原理，同时围绕后级的输出，对LDO的运放，带隙参考基准以及功率调整管展开了描述。
