Latest Patents

One of his latest patents is titled "Two cascoded transistor chains biasing DAC current cells." This invention focuses on designing a precise current cell for digital-to-analog (D/A) converter circuits, compensating for manufacturing process variations. The current cell utilizes a cascoded transistor chain to control output voltage and isolate voltage supply noise. An external bias current is fed into a cascoded biasing string of eight transistors, which are mirrored to the current cell itself. This innovative biasing scheme ensures that very precise current is replicated at the output of the D/A circuit. Additionally, the current cell features improved current steering and a shunt path that minimizes voltage swings during switching, allowing for faster operation while reducing noise coupling.

Another significant patent is the "Low-voltage high-performance dual-feedback dynamic sense amplifier." This sense amplifier circuit includes a voltage developing stage that generates a differential voltage based on first and second data inputs. It also features a full-swing locking stage that latches complementary latched data outputs and a voltage equalization stage that equalizes voltages on data lines. The timing of control signals is carefully managed to minimize power consumption, ensuring efficient operation of the sense amplifier circuit.
