By the way , r8 is a variable resistor and r2 can also be a variable resistor R8的是一個可調(diào)電阻, r2也可以是一個可調(diào)電阻器。
One was adjusted by built - in register , and the other was adjusted by external variable resistor 針對vcom調(diào)節(jié)方式,分別設(shè)計了由ic內(nèi)部寄存器軟件調(diào)節(jié)和外部可調(diào)電阻調(diào)節(jié)法兩種電路。
Recommendations for dimensions of spindle ends and bushes , and for dimensions for the mounting of single - hole , bush - mounted spindle - operated variable capacitors , variable resistors and potentiometers for electronic equipment 電子設(shè)備用軸端和軸套尺寸單孔軸套安裝軸動可變電容器可變電阻器及電位計尺寸的推薦標(biāo)準(zhǔn)
In the fifth chapter , a new fully differential operational amplifier with voltage and current - mode negative feedback has been proposed , which can stabilize its quiescent operation point , using the characteristic of mos transistors which operate in the triode region acting as active variable resistor , a fully differential fourth - order chebyshev low - pass filter with tunable frequency and bessel low - pass filter with accurate group delay based on r - mosfet - c and operational amplifier has been designed 第五章:提出了一種新的既具有電壓共模負反饋又同時具有電流共模負反饋的全差分運算放大器電路,能較好地穩(wěn)定電路的靜態(tài)工作點,并應(yīng)用mos管工作在線性區(qū)可作有源可變電阻用的特性設(shè)計得到了截止頻率可連續(xù)調(diào)節(jié)的高性能r - mosfet - c 、運放結(jié)構(gòu)切比雪夫( chebyshev )和精確群時延值貝塞爾( bessel )低通濾波器。
