Latest Patents

One of his latest patents is a "Simple CMOS threshold voltage extraction circuit." This invention is directed towards a simple and inexpensive circuit designed to extract the complementary metal-oxide-semiconductor (CMOS) threshold voltage (Vt) from an integrated circuit. The threshold voltage can be utilized in various applications, including temperature sensing within the circuit. The CMOS Vt extraction circuit features a current mirror and a configuration of well-matched transistors and resistors, leveraging the square law equation. This design is particularly suited for applications that require low-power radiation-hardened circuits.

Another significant patent is the "Apparatus and method for compensating for process, voltage, and temperature variation of the time delay of a digital delay line." This invention provides a process, voltage, and temperature (PVT) compensation circuit along with a method for continuously generating a delay measure. The circuit comprises two delay lines, each producing a delay output. These delay lines include multiple delay elements, which may consist of current-starved inverters. The outputs are processed by a combining circuit that determines an offset pulse based on the two delay outputs, averaging the voltage to establish a delay measure. This measure can indicate the necessary PVT compensation for input or output signals in various application circuits, such as memory-bus drivers and processors.
