And just the value of the capacitor for amplitude. Adjust input time of square wave for frequency

At 77.6nF you should see the RC transient forming the slope of the saw tooth. As you increase the capacitance that the time to charge is slower than the incoming freqency time . Solve for time is resistance times capacitance.

The purpose of the transitor is to immediately couple the top of the cap to zero volts when turned on. So when incoming pulse goes high. The output drops to 0 volts

When the transitor is off, allows capacitor to charge.

At 2 uF, you should see a nearly perfect sawtooth at 1 kHz

Compare input square wave to output over RL

This isnt a sawtooth generator this is just a simple pulse amplifier and inverter
