DEFINITION

Classification: 326/92

With capacitive or inductive bootstrapping:

(under subclass 89) Subject matter wherein the logic circuit includes discrete, capacitive, or inductive elements or uses its inherent capacitance or inductance to enhance its operating condition, to achieve full driving switching capabilities in response to logic input signals.

(1) Note. Enhancement of the performance of the logic circuit includes boosting the DC level of the gating 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 element to a particular circuit location.
