Title: Innovations of Robert A. Olah
Introduction
Robert A. Olah is a notable inventor based in Sunnyvale, CA (US). He has made significant contributions to the field of electrical engineering, particularly in the development of integrated circuits and flash memory technologies. With a total of 6 patents to his name, Olah's work has had a considerable impact on modern electronics.
Latest Patents
One of his latest patents is a voltage down converter for multiple voltage levels. This invention involves a voltage regulator circuit in an integrated circuit (IC) device, such as a Complex Programmable Logic Device (CPLD). The circuit comprises a reference voltage generator, a tuning circuit, and an output driver circuit. The reference voltage generator converts an external supply voltage into a stable reference voltage. The tuning circuit then converts this stable reference voltage into a desired internal supply voltage, which is essential for deep sub-micron transistors. The output driver circuit ensures that the desired internal supply voltage is delivered with sufficient current to power the IC device's circuits effectively. The tuning circuit includes an operational amplifier (op-amp) and resistive elements configured in a voltage divider setup within the negative feedback loop of the op-amp. By adjusting the resistive elements, a variable internal supply voltage can be achieved.
Another significant patent by Olah is a method to implement flash memory. This invention discloses a plurality of flash electrically erasable programmable read-only memory (EEPROM) cells, where metal lines couple both the sources and drains of the flash cells. The reading process involves applying a positive voltage to the source and reading from the associated metal source line. Additionally, a soft erase scheme is provided to increase the threshold voltage of over-programmed flash cells, preventing leakage caused by applying a positive voltage to the drain.
