There is a type of amplifiers that have several advantages over the standard VFB amplifier at high frequencies. They are called current feedback (CFB) or sometimes transimpedance amps. Most op amp specifications are largely topology independent. Although voltage feedback and current feedback op amps...
ST's op amp portfolio provides a unique choice of high performance, low power and precision operational amplifiers in a wide variety of packages.
Operational amplifier (op amp for short) is basically a voltage amplifying device designed to be used with components like capacitors and resistors, between its in/out terminals, or is simply a linear Integrated Circuit (IC) having multiple-terminals. In electronics, the open-loop voltage gain of...
so even a wideband JFET amplifier may have a very low bias current-values of a few tens of picoamperes are commonplace, and the AD549 has a guaranteed bias current of less than 60 fA (one electron per three microseconds!) at room temperature. ...
运算放大器(op-amp)是放大两个输入之间电压差的集成电路(IC) 由于它是为执行算术运算而开发的,所以如此命名。放大器、缓冲器、比较器、滤波器等可以用简单的外部电路来实现。 运算放大器有五个端子:正电源、负电源(GND)、同相输入、反相输入和输出。通常,这些端子的命名如下所示。(单电源运算放大器的...
