Latest Patent Applications

One of his notable patent applications is titled "DELTA-SIGMA MODULATOR WITH ANTI-WINDUP CIRCUIT." This application describes a delta-sigma modulator that includes a loop filter circuit with a first input for receiving an input signal and a second input for receiving a feedback signal. The loop filter generates a filtered signal, while a quantizer circuit quantizes the integrated signal to produce an output signal. An anti-windup circuit is incorporated to detect when the integrated signal exceeds the input range of the quantizer circuit. In response, it generates a dead zone signal that corresponds to the difference between the filtered signal and the input signal range. The feedback signal is a combination of the output signal and the dead zone signal.

Conclusion

Paolo Stefano Crovetti's work in the field of delta-sigma modulation showcases his innovative spirit and dedication to advancing technology. His contributions, particularly through his latest patent application, highlight the importance of continuous improvement in signal processing techniques.
