Hello, I'm having a final project for an eletronics course.
I have to implement a monostable multivibrator using an 4007 integrated circuit, using MOSFETs. I've started running into difficulties when assembling the circuit in a breadboard after running the simulations on Spice. I tried checking if results in an oscilloscope were matching the simulated ones, but they weren't.
I can't figure out if it's the pin allocation that's simply wrong or I just can't assemble stuff on a breadboard - or both. I've come here since surely there's people that aren't as dim-witted as I am.
The integrated circuit
The integrated circuit I'm using (was given) is an IC4007. For reference, here's the DIP:
Along with the prebuilt connections:
The circuit to implement
This is the monostable multivibrator using NOR/NOT gates I'm trying to do:
To make the logic gates, I've used the following MOSFET with pin-allocations:
Sorry for the crude drawing.
The functions used were:
The breadboard assembly
The result of all of this, in the oscilloscope, is a never-stopping weird shape wave that does not match the simulation. I'm starting to believe that it's an issue with the capacitor and how it's mounted on the circuit.
