Latest Patents

One of Mathur's latest patents is titled "Correcting for offset-errors in a PLL/DLL." This invention addresses the main feedback loop of a PLL/DLL, which receives a reference clock and an output clock as inputs. The system operates to achieve phase and frequency lock of the output clock with respect to the reference clock. The PLL/DLL includes an RS-latch that generates a digital output representing the phase difference between the reference clock and the output clock. A correction block in the PLL/DLL adjusts an electrical characteristic of the main feedback loop based on the polarity of the digital output, thereby minimizing or correcting the effects of offset-errors.

Another notable patent is the "Relaxation oscillator circuit with reduced sensitivity of oscillation frequency to comparator delay variation." This invention features a first current source that generates charging current and a second current source that generates a reference voltage. The circuit includes a resistor, a capacitor, a comparator, a peak detector, and an error detector, all working together to control the charging current, offset voltage input to the comparator, and capacitance of the capacitor. This innovation significantly improves the stability of oscillation frequency in electronic circuits.
