CASCODE CIRCUIT

摘要

A cascode circuit arrangement has a low voltage MOSFET and a depletion mode power device mounted on a substrate (for example a ceramic substrate), which can then be placed in a semiconductor package. This enables inductances to be reduced, and can enable a three terminal packages to be used if desired.

1. A cascode transistor circuit comprising:
a first, depletion mode transistor having its drain for connection to a high power line; a second, silicon MOSFET with its drain connected to the source of the first transistor and its source for connection to a low power line; a substrate on which the first and second transistors are mounted, which has a conductive track providing the connection between the source of the first transistor and the drain of the second transistor.
