Embodiments included herein are directed towards a charge device model ('CDM') protection circuit. The circuit may include a power supply, a power clamp operatively connected to the power supply, at least one diode connected with the power clamp, a field effect transistor (“FET”) operatively connected with the at least one diode and a trigger mechanism configured to activate the FET.

Circuit and method for charge device model protection

A system, a method and circuit arrangements for adjusting an output impedance of an electric circuit involve impedance cells connected to an output terminal in parallel with one another. Each impedance cell includes parallel branches. Each branch includes switching units and resistors. The resistors in a branch are connected in series and contribute to an overall impedance of their corresponding impedance cell. Each switching unit is configurable to selectively bypass a corresponding one of the resistors, thereby calibrating the impedance cell. The output impedance can be set by identifying a combination of calibrated impedance cells that need to be activated in order to produce the target output impedance.
