An apparatus may include global control module, the global control module including a digital master clock generator and a master waveform generator. The apparatus may also include a plurality of resonator control modules, coupled to the global control module. A given resonator control module of the plurality of resonator control modules may include a synchronization module, having a first input coupled to receive a resonator output voltage pickup signal from a local resonator, a second input coupled to receive a digital master clock signal from the digital master clock generator, and a first output coupled to send a delay signal to the master waveform generator.
