並聯放大器英語怎麼說及英文翻譯
『壹』 哪為英語高手能幫我翻譯這段電氣專業英語! 謝謝
對數放大器只是多種運算放大器應用中的其中一項,它的非線性反饋元件被用於發展非線性轉移的傳輸特性。比如,兩個對數放大器可以用於強化兩個不同信號的對數,這些電壓可以相加,然後指數(相加)結果的函數可以用一個換向的對數放大器和用二極體替換的R1組合後被精算。
其最終就形成了一個模擬乘法器。其它的運算放大器操作如限性,矯正峰值檢波,平方根,自乘,除法等等都能用類似的方法進行操作!

1.引言
THE USE of conventional, unsymmetrical amplifier circuits in biomedical engineering is very limited, because of their inadequacy in suppressing power-line interference.常規的不對稱放大器電路在生物醫學工程中的使用是有限的,因為它們在抑制電力線路的干擾上存在不足之處。 Because one of the patient electrodes is directly connected to the amplifier
signal ground and the other is a high impedance point, the interference
current flows only through the grounded electrode. 因為病人的電極中有一個直接連接到放大器信號接地,另一個是高阻抗點,所以干擾電流只流過被接地的電極。The grounded electrode impedance voltage drop is amplified and leads to circuit saturation or masking of the useful biopotential
signal. 該接地電極阻抗的電壓降被放大,並導致電路飽和,或者對有用生物電位信號的掩蔽。
Many biosignal acquisition devices could benefit from the use of only two electrodes. 很多生物信號採集裝置可以通過僅採用兩個電極而得到好處。Electrocardiogram monitoring in intensive care wards, ambulatory monitors, defibrillators etc.
are among the most common examples. 在重症監護病房中的心電圖監控、門診監測器、除顫器等是最常見的例子。
The most widely used technique for biosignal amplification is based on an instrumentation amplifier first-stage design, because of its ability to suppress the common mode interference
(NEUMAN, 1998). 最廣泛使用的生物信號放大技術是基於一種儀表放大器的一級設計,因為它能抑制共模干擾(Neuman,1998)In two-electrode instrumentation, the
amplifier inputs must have a differential impedance that is as high as possible to avoid signal attenuation. 在雙電極儀器應用中,放大器的輸入必須有盡可能高的差分阻抗,以避免信號衰減。On the other hand, the amplifier should have reasonably low common mode impedance, to create a path for the common mode interference
currents without significant voltage drop, keeping both inputs in their specified operating voltage range. 另一方面,放大器的共模阻抗應該合理地低,以便為共模干擾電流創造一個通路而不致有明顯的電壓降,從而將兩個輸入都保持在它們規定的工作電壓范圍內。
THAKOR and WEBSTER (1980) introced a bootstrapped input stage. However, it has an inctive common mode input impedance, resulting in a very poor common mode
input current range, especially for higher frequencies. Thakor和Webster(1980)引入了一個自舉(bootstapped)輸入級,產生了很差的輸入共模電流范圍(特別是在較高的頻率下)
A circuit for a two-electrode, non-differential amplifier was developed (DOBREV, 2002), the performance of which isquasi-equivalent to the differential amplifier described by DOBREV and DASKALOV (2002). Dobrev於2002年開發了一種用於雙電極、無差動放大器的電路,其性能准-等效於Dobrev和Daskalov(2002)所描述的差分放大器。
Because the body as signal
source is floating and, in addition, the modern biopotential amplifiers are isolated, it is possible to drive actively one of the electrodes to the circuit common potential and thus to
balance the flowing interference currents. 因為作為信號源的人體是浮動的,而且現代的生物電位放大器是隔離的,所以有可能主動地將電極中的一個激勵到電路的公共電位,並因此來平衡流過的干擾電流。
Now, a very simple, low-cost circuit of a two-electrode nondifferential
amplifier is suggested, where the interference current balancing is achieved by one operational amplifier
(OA) and two parallel RC networks.現在人們提出了一種很簡單而又廉價的雙電極、無差動放大器的電路,其中,干擾電流的平衡是靠一個運算放大器(OA)和兩個並聯的RC(阻容)網路實現的。

『柒』 關於功率放大器的英文翻譯,專業高手進
這段文字,語法上問題較多,有的專業術語也查不到,但我盡力翻了,供樓主參考。
Power amplifier's input stage is used shoot follower as buffer input. 功率放大器的輸入級用發射跟隨器(shoot follower)作為緩沖器輸入。Second stage is used difference circuit as small signal voltage amplifier stage. 第二級採用差分電路作為小信號電壓放大器級。Set electricity stage as constant current source loading. 將電氣級設定為恆定的電流源負載。There is higher voltage gain and indissoluble work, small nonlinear distortion. 存在較高的電壓增益和不能分解的功,以及小的非線性失真。 Third stage's main voltage amplifier stage is used sharing shoot stage circuit. 第三級的主電壓放大器級採用共享的射發射級電路。Set electricity stage loading also is constant current source. It can make signal voltage amplifier to large enough. 同樣將電氣級負載設定為恆定的電流源。它可使信號電壓放大器足夠大。Between second and third stage also is used shoot follower to isolate. 在第二和第三級之間,也採用發射跟隨器來隔離。Fourth stage is output push stage. 第四級是輸出推挽級。Shoot follower is consisting of complementary middle-power double tubes, which are both installed on main radiator with bias control tube together. 發射跟隨器由補充的中功率雙管構成,它們都與偏置控制管一起安裝在主輻射器上。Such has good temperature compensation and make output stage work steadily. 這樣有良好的溫度補償作用,而且使輸出級穩定工作。Fifth is power output stage, is consisting of 150W Toshiba mutual-complementing double tubes (C5200/A1943), when working in Ⅰstate, there are higher efficiency and strong output power. 第五級是功率輸出級,它由150W的東芝互補雙管(C5200/A1943)構成,當在電流(I)狀態下工作時,具有較高的效率和強的輸出功率。
