Abstract: An acoustic cleaving system are described for initiating and controlling crack propagation. In an embodiment, the system includes an acoustic generator that includes a piezoelectric device; a high-voltage power supply; and an acoustic cleaving circuit. The acoustic cleaving circuit includes a push-pull circuit coupled to the piezoelectric device and coupled to the high-voltage power supply, and a capacitor bank that includes one or more capacitors coupled in parallel to the push-pull circuit. In one embodiment, the push-pull circuit is for receiving at least one input signal and for producing an amplified output signal to drive the piezoelectric device.
