Latest Patents

One of Jiawei Xu's latest patents is a light-to-digital converter. This device comprises a light-to-current converter, a current integrator with an integrator output that is resettable to a baseline level, and a counter with a digital output. The light-to-current converter is switchably connectable as a positive integration input to the current integrator, allowing for the integration of a current during a light-collecting phase. The integrator output starts from a baseline value and ends at a value to be digitized. Additionally, a reference current source is switchably connectable as a negative integration input to the current integrator, facilitating the integration of a reference current during a subsequent counting phase. The counter is configured for measuring the time spent integrating the reference current.

Another significant patent is a device for the read-out of a photoplethysmography (PPG) signal. This device includes a photodiode configured to detect a PPG signal, along with read-out circuitry for reading the signal. The input stage is designed to receive input signals from the photodiode terminals and a DC bias voltage, enabling current sensing to provide fully differential amplification of the input signals. The output stage generates a differential output voltage through a gain component, effectively capturing both AC and DC components of the PPG signal.
