Transient-to-digital converter to detect electrical fast transient (EFT) disturbance for system protection design

New on-chip 4-bit transient-to-digital converter for electrical fast transient (EFT) protection design has been proposed. The converter is designed to detect EFT-induced transient disturbances and transfer different EFT voltages into digital codes under EFT tests. The experimental results in silicon chip have confirmed the successful digital output codes.
