Voltage Spikes in Integrator CKT
Notice my first post where I said that I dropped different op-amps in with slower slew rates and still saw the effect. So either all op amp models in PSPICE have this glitch, or it actually does exist in the real circuit. The input rise time and fall times are on the order of 40 and 70 ns.- hevykevy

Voltage Spikes in Integrator CKT
A few things I need to clear up: 1.) The circuit is being generated on PSPICE, and is not built at the moment. All problems are being reported from P-SPICE, and not live data. 2.) Don't worry about the DC drift it is taken care of and like many of you said, does not pertain to this problem...- hevykevy

Voltage Spikes in Integrator CKT
nbucska, the polarity of the spike is the same as the polarity of the output waveform. Therefore, the spike adds to the peak to peak value of the entire waveform.- hevykevy

Voltage Spikes in Integrator CKT
Hello all, I am having a small problem with a square-wave driven integrator circuit. The details are as follows: Input voltage: +/- 2.5 V square wave at 24kHz 50% DC Feedback Cap: 4700pF Input Resistor: 2.55k Configuration: Inverting Power Rails: +/- 2.5 V Desired output: 24kHz triangle wave...- hevykevy

Single frequency generator
IRStuff, I have tried to do some testing using just the "real thing" and have found that it is quite difficult to monitor the signal at the low power levels I want to read. This problem is mainly due to the constant shifting in the frequency of a DSSS signal. I would like to...- hevykevy

Single frequency generator
Hello, I'm looking to either build or purchase a device that simulates a signal from an 802.11b WLAN card. Does anyone know of any companies that supply this type product? Does anyone know of any simple solutions for building this type of generator? Basically, I am doing some testing with...- hevykevy
