Abstract: A chip for controlled electrostatic discharging to avoid loading on input/output pins, comprising: a die comprising: a first plurality of connector pins each conductively coupled to one or more signal paths, each of the first plurality of connector pins having a first height; and a second plurality of connector pins independent of any signal paths, each of the second plurality of connector pins having a second height greater than the first height.

Abstract: A system and method for detecting and measuring electrostatic discharge during semiconductor assembly are described. A semiconductor device fabrication process forms a conductor between two metal routes in a series path on a semiconductor die. The series path is between a bump on the die and a substrate tie. The two metal routes have a width greater than a threshold based on a metal width capable of conducting a critical current density caused by an electrostatic discharge event without conductive failure or breakdown. The conductor has a width less than the threshold. When an electrostatic discharge event occurs, if the current exceeds a critical amount of current, the conductor experiences conductive breakdown and current ceases to flow. During later testing, this series path is tested for open connections, which indicate whether the conductor acting as an electrical on-die fuse experienced conductive failure during assembly of a semiconductor chip.

Abstract: Apparatus and methods are provided for calibrating and operating a receiver circuit. An exemplary method comprises the steps of applying a first voltage offset to a first input of an amplifier circuit, generating an output signal at an output of the amplifier circuit based on the first voltage offset and a second voltage offset at a second input of the amplifier circuit, adjusting the second voltage offset based on the output signal, and maintaining the second voltage offset at a constant voltage when the output signal is indicative of the second voltage offset cancelling the first voltage offset.
