Various examples are provided related to supercascode power switches that can be used in, e.g., HV and MV applications. This disclosure introduces a cascaded supercascode (CSC) power switch which can include a series of unit supercascode (USC) circuits; a control switch coupled in series with the series of USC circuits; and an external balancing network coupled to each of the n USC circuits. The series has a plurality of USC circuits, with each of the USC circuits including first and second switches coupled in series and an internal balancing network coupled across the first and second switches. A source of each of the USC circuits is a source of the first switch. The internal balancing network can include a capacitor connected between a gate of the second switch and the source of the first switch and a diode connected in parallel with the capacitor.

High voltage cascaded supercascode power switch

Disclosed is an integrated circuit packaging system that includes first and second microchips. Each microchip includes a top surface, a surface, one or more quilt package nodules fabricated on said top surface, and one or more bottom surface connectors. The system also includes a substrate to which the first and second microchips are mounted. The first and second microchips are connected via the quilt package nodules.
