Latest Patents

One of his latest patents is focused on sense amplifiers with high voltage swing. This invention includes a reference voltage generator that produces a reference output voltage and a core output voltage generator that creates a core output voltage. The design incorporates a core front-end stage and a core back-end stage, or a series of amplifier transistors that conduct a portion of core current through a current conducting device, such as a core cell. The specific sizes and connections of the transistors lead to a high voltage swing, enhancing the sensitivity of the sense amplifier.

Another significant patent by Venkatesh pertains to current sensing architecture for high bitline voltage, rail-to-rail output swing, and Vcc noise cancellation. This circuit arrangement allows for the reading of current flowing through a memory cell when voltages are applied. The current is influenced by the charge stored within the cell, which represents the information stored. This technology is not limited to memory applications but can be utilized in any scenario requiring current sensing with a regulated supply voltage.
