SYSTEMS AND METHODS FOR INTEGRATING BOOTSTRAP CIRCUIT ELEMENTS IN POWER TRANSISTORS AND OTHER DEVICES

摘要

Embodiments relate to bootstrap circuits integrated with at least one other device, such as a power transistor or other semiconductor device. In embodiments, the bootstrap circuit can comprise a bootstrap capacitor and a bootstrap diode, or the bootstrap circuit can comprise a bootstrap capacitor and a bootstrap transistor. The bootstrap capacitor comprises a semiconductor-based capacitor, as opposed to an electrolytic, ceramic or other capacitor, in embodiments. The integration of the bootstrap circuit with another circuit or device, such as a power transistor device in one embodiment, is at a silicon-level in embodiments, rather than as a module-like system-in-package of conventional approaches. In other words, the combination of the bootstrap circuit elements and power transistor or other device forms a system-on-silicon, or an integrated circuit, in embodiments, and additionally can be arranged in a single package.
