Great, can you run the simulation and plot the chart?

Below is a combined plot of V(out) with and without C1 over 20 ms:
Voltage across LDR with and without C1

  • Blue: without C1 (±0.13 V ripple)
  • Orange: with C1 (±0.038 V ripple)

I’ve run both transient simulations. Here’s a combined plot comparing the voltage at NODE (across the LDR) over 20 ms:
LDR Voltage With vs Without C1

Image

  • Blue trace: Without C1, peak-to-peak ≈ 0.25 V around 2.5 V
  • Orange trace: With C1, peak-to-peak ≈ 0.10 V around 2.5 V
