Latest Patents
One of his latest patents is the "High Band Width Emitter Coupled Logic Gate." This invention includes a basic current switch logic block and emitter-follower output transistors. A switchable active circuit current sink is connected between an internal voltage switching node associated with the current switch logic gate and the emitter terminal of the emitter-follower output transistor. This active current sink is switched between a relatively low conductive state to a relatively high nonsaturating conductive state to maintain substantially constant current flow through the emitter-follower output transistor during switching. This innovation significantly improves AC beta roll-off characteristics.
Another notable patent is the "Current Mode Logic Circuit." This circuit provides AND/OR type functions while substantially eliminating '0' voltage level changes and spikes without sacrificing switching speeds. By omitting conventional emitter and collector-dotting between the logic input gates and an emitter-follower output stage, the design employs diode loads for generating reduced signal swings for driving the output gate. Although the output gate contains more devices than a single emitter-follower output stage, the reduced signal swing and a push-pull drive mode for the output gate offset any increased switching times, achieving the overall objectives without sacrificing switching speed.
