DEFINITION

Classification: 327/390

With capacitive bootstrapping:

(under subclass 389) Subject matter wherein the IGFET switching circuit includes discrete, capacitive elements, or uses its inherent capacitance to enhance its operating condition, to achieve full switching capabilities in response to control signals.

(1) Note. Enhancement of the performance of the switching circuit includes boosting the DC level of the control signals for one or more semiconductor devices, as well as boosting the attained DC levels of individual circuit nodal locations, usually by, for example, either a feedforward/feedback connection or a separate time-related, pulse signal coupled via the boosting capacitor to a particular circuit location.
