Latest Patents

One of his latest inventions is the GaAs SCFL RAM, which features a unique three-voltage-level write circuit and direct-read circuitry that minimizes gate delay. This RAM design allows for various configurations, including 1K×16 and 16K×1 memory setups. It incorporates strobe circuitry that enables the powering down of selected memory modules without data loss, effectively reducing power dissipation. The SCFL circuitry is designed for fast switching with minimal current spiking, offering a wide range of threshold voltage tolerance and excellent noise margins, along with high resistance to radioactive radiation.

Another significant invention by Joseph is the angle digitizer with enhanced harmonic rejection. This device converts time-varying signals representing sin(θ) and cos(θ) into an n-bit digital signal. The angle θ can vary over a range, typically 2π radians, and is segmented into 2^(n+1) - 4 segments. The segments are mapped into 2^(n) - 1 amplitudes, encoded as the n-bit digital signal. This invention is particularly beneficial for applications requiring precise phase difference measurements between input and reference signals, enhancing harmonic rejection through efficient amplitude state distinction.
