So they gave the mice a different drug that mimics a natural chemical produced during exercise, called AMP.

所以他们给了老鼠另外一种叫AMP的药，其效果在训练时如同一些天然激素。

The rat generator operates at the femtowatt scale -- a pico-amp is a million millionth of an amp, so it is a tiny amount of current -- so not very much power.

大鼠发电机以毫微微瓦级在运转（1微微安培是1安培的亿万？ 分之一），因此它只是极少量的电流，产生不了多少电力。

So to run with a single amp section you need the DAC to be single ended and to run the noise shapers at much higher rates to reduce your filtering requirements.

要同单端放大部分一起工作，DAC必须是单端的，且整形滤波必须处于非常高的频率以减少滤波需求。
