运算放大器声场展宽电路,Op-amp circuit 关键字:运算放大器声场展宽电路 运算放大器声场展宽电路 家庭影音设备已非常普及,然而有的家庭环境仍不很宽敞,音箱摆放唯以达到标准距离,两音箱几乎是放在影音设备的两侧,这样立体声的听感较差。若在扩声机内加装一个声场展宽电路,听感会大有改善。笔者试装了这个展宽电路,接...
The equivalent circuit of an op-amp is the circuit where the op-amp parameters are represented in terms of physical components. Such a representation is very helpful for analysis purposes. Below, you can find the equivalent circuit of theop amp. Circuit parameters like the internalresistance, ou...

An OP-amp circuit includes a first circuit unit configured to generate an operating voltage in response to an enable signal, a second circuit unit configured to amplify a difference between respective voltages received through an inverting terminal and a non-inverting terminal in response to the ...
Op-amp Basics (part 1): Operational amplifiers (op-amps) are some of the most important, widely used, and versatile circuits in use today. The first op-amp used vacuum tubes and was released in 1941 by Bell Labs. The ubiquitous ua741 was released in 1968
Also, the achievable amplifier gain is often quite low in such a technology, since cascoding may not be a practical circuit option due to the resulting reduction of the output signal swing. In this paper, some old and some new circuit techniques are described for the compensation of the ...
This diagram demonstrates one method of introducing hysteresis into a comparator circuit. Summary A comparator generates an output signal that indicates which of two input signals has the higher voltage. An op-amp can function as a comparator because it combines a differential input stage with very...
amp circuit which is called as a differential amplifier. It is basically used as a building block of an operational amplifier which is called asoperational amplifier (op-amp). The main function of the differential amplifier is, it amplifies the changes between two i/p voltages. But, conquers ...
