Abstract
Certain aspects of the present disclosure provide a voltage transient detection circuit. The circuit generally includes a first switch having a first terminal coupled to an input signal source node, and a second switch having a first terminal coupled to the input signal source node. The apparatus includes a first shunt capacitive element coupled to a second terminal of the first switch, a second shunt capacitive element coupled to a second terminal of the second switch, a differential circuit having a first input coupled to the second terminal of the first switch, a second input coupled to the second terminal of the second switch, and an output coupled to an output node of the voltage transient detection circuit. For certain aspects, the apparatus also includes a first current source (selectively) coupled to the first shunt capacitive element and a second current source (selectively) coupled to the second shunt capacitive element.
