With a total of 2 patents to his name, Schifmann's work showcases his innovative approach to solving complex engineering problems.

Latest Patents

One of Schifmann's latest patents is a "Method for mitigation of droop timing errors including a droop detector and dual mode logic." This technique addresses timing errors induced by power supply droops through an inverter-based droop detector and Dual Mode Logic (DML). The droop detector utilizes capacitor ratios, making it less sensitive to Process/Voltage/Temperature (PVT) variations and random offsets compared to prior art. The DML adjusts its power/performance ratio based on the droop level input from the detector, ensuring that critical timings are preserved.

Another significant patent is the "Method to utilize mismatch size to produce additional stable bit in tilting PUF." This method involves creating a PUF bit for use with transistor circuitry by performing a tilt test on a PUF cell. The test compares the mismatch of the PUF cell's response to a tilt threshold, determining the magnitude of the mismatch. This random mismatch magnitude serves as an entropy source to produce at least one PUF bit, referred to as a mirror PUF bit.
