Classification: CPC H | IPC H

Claim 16:
17. The microelectronic device of claim 14, wherein the voltage discriminator includes:
an input buffer coupled between the blocking capacitor of the high bandwidth detector and the reference line, wherein an input of the input buffer is coupled to the input high-pass filter, the input buffer having a buffer output line; and
an output FET having a source coupled to the buffer output line, a drain coupled to the first output line of the voltage discriminator, and a gate coupled to the input high-pass filter, the output FET of the voltage discriminator being configured to provide a high impedance condition on the first output line of the voltage discriminator when a second overvoltage transient occurs on the protected line, the second overvoltage transient being characteristic of a voltage surge event.
