Electrostatic discharge event and transient signal detection and measurement device and method
View Patent ↗An electrostatic discharge (ESD) event and transient signal detection and measurement device and method are described. The device and method are able to distinguish between an ESD event and other non-ESD events.
1. A device for identifying an ESD Event, comprising:
a receiver that receives an input signal;
an identifier unit that compares the received input signal to a predetermined signal in order to determine if the input signal is an ESD event signal; and
an output circuit for outputting an identification signal if the input signal is identified as an ESD event signal,
wherein the received input signal has a spectrum having a predetermined amount of energy at one or more frequencies and wherein the identifier unit further comprises a spectrum detector that compares the spectrum of the received input signal to a spectrum of an ESD event signal.
2. The device of claim 1 wherein the received input signal has a signal envelope and wherein the identifier unit further comprises an envelope detector that compares the signal envelope of the received input signal to a signal envelope of an ESD event signal.
3. The device of claim 2 , wherein the envelope detector further comprises a window comparator circuit.
4. The device of claim 1 , wherein the receiver further comprises an antenna.
5. The device of claim 1 , wherein the received input signal has a signal envelope and wherein the identifier unit further comprises a processor that executes a pattern recognition software module that compares the input signal envelope pattern to a predetermined signal envelope.
