Question

Describe thoroughly this free-running sawtooth generator that uses a Bootstrap ramp generator and a Schmitt trigger. Explain the process in the Bootsrap ramp generator and in the Schmitt trigger. Note that the output of the ramp generator is a ramp waveform, which in turn, is the input of the Schmitt Trigger. Explain also the function of each components, especially the charging and discharging C2 and C1 capacitors. The two op-amps are LM358 with supply voltage ±12V for an output of 0V to -10V (UTP = 0V, LTP = -10V).

Note: I need a long explanation please. I want to really learn from this.
