Our next basic op amp circuit project can be seen in the above figure. It is an electret condenser microphone amplifier circuit. In this design, the op amp is operated in an inverted adjustable gain amplifier circuit with a low potential electret microphone feeding the input. Take note that t...
The above linked article contains all the basics of op-amps, with the basic op-amp circuit with two transistors. The different advantages of op-amps are also specified, along with links to different basic op-amp circuits like Comparator Circuit, Schmitt Trigger Circuit, Astable Multivibrator, Mon...
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...

Complementary current mirrors receive the differential signals out of the first stage and combine them at a common output node for amplification by an output buffer. The circuit can be operated at low power and produces a high slew rate.
The present invention relates to an operation based on a bandgap reference discharge circuit, the overall circuit with Miller compensated two-op-amp. 此运放采用两种办法来减小失调电压,一是输入对管采用工作在亚阈值的NMOS管,二是电流镜负载采用过驱动电压较大的共源共栅PMOS管. This amplifier uses two ...
