- how to add OP amp 741 to LT spice - All About Circuits
hello everyone Can anyone tell me how to add OP amp 741 to LT spice simulation tool
- Ideal Op amp differential in cadence - Forum for Electronics
ideal op amp you can write a ideal opamp with AHDL verilog-A in Cadence by yourself, or you can find it in a AHDL library which provided by cadence
- How to reduce an offset in Op-Amp? | Forum for Electronics
Hi, i am trying out a simple op-amp (pmos input diff pair followed by a pmos source follower) I find that the offset is very high any ways to reduce the offset ? I know why this offset occurs but dont know how to overcome it
- Opamp over voltage circuit - All About Circuits
Hi Can anyone help me with how this circuit works? what is this Opamp configuration?
- OpAmp - LTspice XVII - All About Circuits
I was trying to simulate some opamp circuit in LTSpice and was coming to a dead end everywhere I did some trouble shooting and finally landed on a strange behaviour Attached is a simple asc file of an opamp with the + input tied to output, - input grounded Under this condition, afaik
- what is difference between OTA and OP-amp? - Forum for Electronics
difference between op amp and other amplifiers OTA is a TRANSCONDUCTANCE amplifier which means that it's GAIN is given by Io Vin=A (For a certain Voltage input you will have an output current Io which will be A times Vin) This means that the output current is independent of your load value (in theory) an OPAMP is a Voltage to Voltage amplifier Its GAIN is given by Vo Vin=A, which means that
- about the ICMR of a opamp | Forum for Electronics
in all of ic design books,the authors says that the ICMR of a opamp is very important in opamp designing But this always causes me confusing I think we always give the opamp a fixed input common mode level,e g 1 2Vdd Then why should we take the ICMR into account? In our project,the issue of a
- What are some modern 741 Op Amp Equivalents? - All About Circuits
Just about any "modern" opamp is going to have better specs than the 741 (e g wider input and output voltage ranges, faster slew rate, higher GBW), but they'll cost more than a 741 and will likely have a smaller operating voltage range If you know how to use them, 741 will still do what they were designed to do
