With a total of 2 patents to his name, Vail's work has had a lasting impact on the industry.

Latest Patents

One of Vail's latest patents is the "Three-state digital mixer-driver circuit." This innovative circuit operates within a code correlator of a spread-spectrum communications system. It simultaneously multiplies an input RF signal with two phase-offset digitally encoded bit streams. The design features a double-balanced mixer that is driven by the difference of the digital signals, allowing the mixer to be either inverting, noninverting, or off. Matched ECL bistables reclock the phase-offset bit streams, while a load current steering circuit provides a balanced, differential drive current to the mixer. This configuration enables the mixer to switch states faster than the bistables alone. In another embodiment, a single bistable receiving an encoded bit stream differentially drives the mixer in a biphase circuit.
