This is a voltage multiplier circuit. First circuit is used to double the a square wave (any amplitude). However there is minus about 2v losses in base-emitter of the transistors and the diodes in first circuit.
To work, second circuit must fall to nearly 0.4v and rise to at least 5.6v. to prevent short-circuiting and both …
