Exponential-edge transmission line pulsing for snap-back device characterization

A new ESD testing system, the exponential-edge transmission line pulse system (EETLP), is presented. EETLP generates 100ns square pulses with a variable, exponentially decaying falling edge. When applied to an ESD protection device, the pulse shape allows for capture of both the transient and quasi-steady-state responses, in the context of a single measurement. EETLP provides unprecedented insight into the turn-off dynamics of snapback-type devices. Device measurement data are presented to demonstrate the capabilities of EETLP.
