unity-gain amplifier 中文意思是什麼
unity-gain amplifier
解釋
單位增益放大器-
The amplifier was being used as a unity gain buffer with an electrochemical cell and the non - inverting input was connected to a platinum electrode and to nothing else
該用戶的電路中，放大器用作緩沖器，其反相端除了與電池的一個白金電極相連之外，沒有其他電氣連接。 -
In such cases, the unused amplifier should be connected as a unity - gain follower ( force and sense pins tied together ) and the input should be connected to ground
同樣的原因，不用的放大器應當成單位增益跟隨器（驅動端和感測端接到一起） ，且其輸入端應接地。 -
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。
