Abstract: A method and circuit for providing a soft start-up process for an amplifier circuit to reduce or prevent destructive overshoot of an output voltage are provided. In accordance with an exemplary embodiment of the present invention, an exemplary method and circuit are configured to suitably momentarily replace an actual fixed reference voltage with a second reference voltage during the start-up process. Such a method and circuit can provide a fast start-up process without destructive overshoot and without affecting or compromising any control loop of the amplifier circuit, and can be configured within various applications. In accordance with an exemplary embodiment, an exemplary amplifier circuit is configured with a soft-start circuit, with the soft-start circuit configured to provide a secondary reference voltage during initial start-up before switching to an actual reference voltage.

Abstract: One embodiment provides a system for protecting at least one component in an integrated circuit (IC). The system includes a disconnect element that is electrically connected in series between an input terminal of the IC and the at least one component. The disconnect element is configured to have a first state to electrically connect the terminal to the at least one component and a second state corresponding to a high impedance condition that electrically isolates the terminal relative to the at least one component. A control system is configured to cause the disconnect element to transition from the first state to the second state in response to a rate of change of an input signal at the terminal exceeding a predetermined rate of change.

Abstract: One embodiment provides a system for protecting at least one component in an integrated circuit (IC). The system includes a disconnect element that is electrically connected in series between a terminal of the IC and the at least one component. The disconnect element is configured to have a first state to permit an electrical signal to propagate from the terminal to the at least one component and a second state corresponding to a high impedance condition that electrically disconnects the terminal relative to the at least one component. A control system is configured to cause the disconnect element to transition from the first state to the second based on at least one predetermined activation condition.
