+
+<p>
+  Here is an example of a boost converter circuit configured for SPICE
+  simulation. It uses one voltage source (`V2`) with a square wave to drive
+  a MOSFET, boosting the voltage from a 5V DC source (`V1`) to a higher
+  level. Voltage probes are placed at the input and output to observe the
+  results.

+<p>
+  The simulation results would show the output voltage across `R1`
+  successfully "boosted" compared to the 5V input from `V1`. The specific
+  output voltage depends on the duty cycle of the MOSFET driver `V2` and the
+  component values.
