OVERSHOOT CURRENT DETECTION AND CORRECTION CIRCUIT FOR ELECTRICAL FAST TRANSIENT EVENTS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18522644 titled 'OVERSHOOT CURRENT DETECTION AND CORRECTION CIRCUIT FOR ELECTRICAL FAST TRANSIENT EVENTS
Simplified Explanation
The positive overshoot detection circuit described in the patent application includes a transistor coupled to a current mirror, a reference current source connected to the current mirror, and a comparator that compares the current mirror's current to the reference current source's current. The output of the comparator indicates whether there is an overshoot in the current. Additionally, a clamping circuit is used to control the transistor's current terminal.

Original Abstract Submitted
A positive overshoot detection circuit comprises a transistor coupled to a current mirror, a reference current source coupled to the current mirror, and a comparator coupled to the reference current source and the current mirror. The comparator output indicates whether the current mirror's current is greater than the reference current source's current. A control input and a current terminal of the transistor are coupled to a clamping circuit. A negative overshoot detection circuit comprises a biasing sub-circuit coupled to a transistor, a resistor coupled to the transistor, and a comparator coupled to the transistor and the resistor. The comparator output indicates whether the transistor is in an on or off state. The biasing sub-circuit is coupled to a clamping circuit. In some implementations, the comparator outputs from the positive and negative overshoot detection circuits are provided to a driver circuit, which modifies its operation.
