Latest Patents

One of Das’s patents, “Circuit for Avoiding Contention in One-Hot or One-Cold Multiplexer Designs,” describes a symmetrical circuit design for an n-to-1 transmission-gate multiplexer. It uses consistent NAND-gate logic on the select lines and reverse-polarity control signals to preserve multiplexer functionality while addressing uneven delays and contention risks associated with asymmetrical designs.

Another patent, “Edge-Triggered Dual-Rail Dynamic Flip-Flop with an Enhanced Self-Shut-Off Mechanism,” describes a shut-off circuit that isolates the flip-flop’s output terminals from internal circuitry during part of the evaluation phase. This isolation helps prevent noise and residual charge from affecting output signal levels.

The supplied information lists 3 patents for Das.
