signal margin 中文意思是什麼
signal margin
解釋
信號余量-
Noise margin refers to the maximum noise voltage that can be added to the generated signal in a digital circuit before an undesirable change is caused in the circuit output
噪聲極限就是指可以加在數字電路的正常信號上，而又不對正常輸出造成危害的最大噪聲。 -
To make use of the maximum signal margin with the maximum scanning distance tolerance, the switching threshold should be set at the mid - way point between the background and mark signals
在使用具有最大掃描距離偏差的最大信號邊限時，轉換門限應該設置在背景與標識信號的正中間？ -
Usually the low power operational amplifier is designed with rail to rail output stage, whose signal dynamirange is small, its output driving force is not strong, here it is designed with voltage displacement stage, and the strong driving force and the low power consumption in this circuit are achieved. with 5v single power, this amplifier consumes only several a, 100khz unity - gain frequency, achieves 80db dc open gain and 55 phase margin for a 100pf load capacitance and a 1m load resistance and other advantages
通常設計的低功耗軌對軌輸出運算放大器中，由於信號的動態范圍比較小，它的輸出驅動能力不強，這里設計的是採用電平位移電路同時實現了電路的強驅動能力與低功耗，它具有在單電源電壓5v的條件下，靜態工作電流只有幾微安，單位增益帶寬達100k ，開環增益能達80db以上，相位裕度也能達55度，輸出源沉電流達500微安以上等優點。
