[SIZE=16px][FONT=Helvetica Neue]Hi, I have been using Semiconductor Parameter Analyzer Agilent 4156B for 1 year. Since a month it is malfuntioning. I am not getting the required IV for my Resistive Random Access Memory (RRAM) devices. To confirm, I checked my devices using some other lab's...

I would like to thank everyone for your sincere comments. You helped me a lot. As I had wasted a lot of time on this circuit but still it didn't work. So I decided to make another citcuit just by changing the resistors to 2.2KOhm. May be there was some wiring mistake or something else in...

Thanks a lot Sir, I'll try it.

Should I just insert a resistor in between + input and ground? or I have to make some connection with Vcc also?

I understood what you mean by lifting +input from ground. But will you explain me how with a 2K2 resistor. If possible with a ckt diagram please.

Sorry Sir, I didn't get you. Will u please explain it. Thank you.

Thanks for your reply. Yes I am using an oscilloscope. Even i tried with a square wave, but still faced the same problem. I can just see a clipped wave. As I raise DC input. The input sine wave rises a little and starts clipping just before 1 volt rise. In real it should start clipping near 12V...

Hi everyone, I am trying to make a Summing Amlifier. I have simulated on computer where it is working correctly, but on real circuit it is showing some mal functioning. I am using OP 27 Op Apmp. The circuit diagram is attached. When I try to add DC voltage to AC sine wave, initially sine wave...
