Online simulation of the пилообразный генератор на чипе 555 circuit

This is a simple sawtooth generator that uses a 555 timer chip. The timing interval begins when the trigger input ("TR") drops below 1/3 V in, or 3.33V. When this happens, the 555 output goes high, and the 555 waits for the threshold input ("th") to reach 2/3 V in, or 6.67V. A PNP transistor acts as a current source to charge the capacitor at a constant rate. The threshold input slowly rises until it reaches the required level. Then the timing interval ends, and the capacitor discharges quickly through the "dis" input. When the capacitor is discharged enough that the trigger reaches 3.33V, a new timing interval begins. The end result is a sawtooth wave.
