1. Hello People, For a project I need to design, simulate and demonstrate a second order Delta-Sigma ADC (only the analog part of the converter).The simulation will be done on multisim and the ADC will be demonstrated using a breadboard platform. An oscilloscope will be used to view the input/output and a function generator can be used as a clock. The input frequency is to be less or equal to than 100Hz.
2. The attempt at a solution:
   Two integrators are required .I believe I need to compare the analog output from the integrator to a reference voltage in order to produce a two level signal. The 1-bit memory element should incorporate a clock in order to time the outputs. I am asking for some directions and some component recommendations.
   Any kind of help would be greatly appreciated.THANKS!

 

Update:
I found this multisim simulation but I'm not sure how to separate the 2nd order circuit from this. Please help
