Source,sink, and bipolar versions can also be designed with a single op amp and some resistors (Figure 1). The Figure 1 Circuits A, B, and C are constant-current sinks offering different compromises among precision, dynamicimpedance, and compliance range. Circuit D is a bipolar current ...
design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements...
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...
My Op-Amp output in Circuit Lab outputs 12 Volts but in real life, I'm only getting 7.7 volts. I know that one op-amp rule is the voltages are the same at the inputs but my LM358 is not meeting that. I have the positive input wired at 12V. I have the gain set at 3 (56K/...

As seen from the circuit symbol above it has two input power supply terminals +VCCand –VCC. For the operation of an op-amp a dual polarity DC supply is essential. In the dual polarity supply, we connect the +VCCto the positive DC supply and the –VCCterminal to the negative DC supply...
Then again, you make what the simulator says and then measure it in real life and it's still someway out, and that's because of device tolerance, and the sub-circuit only has one set of "typical" values. But they put all their faith in op-amps, don't they?
These currents become very large at high frequencies and introduce the main source of errors in these circuits. The equations of the non-ideal currents are given in the paper and based on these, an improved op-amp power-supply current sensing circuit can be obtained...
