1. The problem statement, all variables and given/known data 2. Relevant equations 3. The attempt at a solution I am doing page 4 of the lab attached, and I am trying to simulate the relaxation oscillator in Figure 2. However, I am not getting a square wave like the lab suggests I should get. I have been able to do the derivation at the bottom of the page. I have attached my multisim diagram as well as my transient analysis of the probe at the output of the op-amp. What is going on here?? Based on my calculation of the period T, using R=1000 Ω and C = 100 μF, I get a period of .220 seconds, and here the spacing between the ''squares'' (which are not very squarey) is slightly under 4 seconds. It also goes above my rail of 5 V. I'm also stuck on the derivation on page 6, Vout = -∫Vin/RC dt and proving that it outputs a triangle wave from a square wave.
