Latest Patents

One of Vinod's latest patents is a low-power data acquisition system and sensor interface. This innovative sensor interface includes an on-chip relaxation oscillator circuit and a phase-locked loop (PLL) that work together to generate a highly accurate clock signal using low-power components. The system utilizes a photodiode to generate a current signal based on an optical signal that represents sensor data. An analog-to-digital converter (ADC) processes this current signal to produce a digital signal, which is then analyzed by a processor to estimate various environmental and biomedical characteristics, such as temperature and heart rate. Additionally, the design incorporates an amplifier to enhance the photodiode's current signal and may utilize current digital-to-analog converters (CDACs) to minimize noise sensitivity.

Another significant patent is the tri-level digital-to-analog converter. This invention outlines methods and systems for converting a digital input signal into an analog output signal. The process involves a first delta-sigma modulator that generates a common mode control signal, which is then used by a data delta-sigma modulator to produce a modulated digital input signal. The system includes a shuffler that combines these signals, leading to a digital-to-analog converter (DAC) with tri-level unit DAC elements that generate the final analog output signal.
