A Versatile Large-Signal High-Frequency Arbitrary Waveform Generator Using GaN Devices

Waveform generators are required for a wide range of application including industrial and biomedical areas. Traditionally, these systems usually aimed at generating high frequency signals but with low amplitude levels, making them unfeasible for large-signal real operation analysis. Advances in wide bandgap semiconductors together with digital control enables the design of new systems. This paper presents the design of a 2000-V versatile large-signal high-frequency arbitrary waveform generator taking advantage of GaN devices. The proposed system has been designed and implemented, proving the feasibility of this proposal.
