Many electronics circuits and projects for learning in simple ways.

Ramp Generator circuit using 2N4891 FET

This be Ramp Wave Generator Circuit by use UJT , 2N4891 numbers are important equipment. By Q2 take Voltage of C1 and give Output be sawtooth waves . The R3 will control occurrence waves sawtooth rate by signal picture has will the character is waves , the alms is Voltage quietly increase until sawtooth picture until be high class Voltage topmost that about 5.4V by use power supply Voltage 9V. I hopes this circuit may is born the advantage and friends.
