Paolo Pesenti

Title: Paolo Pesenti: Innovator in Digital Signal Processing

Introduction

Paolo Pesenti is a notable inventor based in Senago, Italy, recognized for his contributions to digital signal processing. With a total of 13 patents to his name, he has made significant advancements in the field, particularly in the development of synchronization devices and delta-sigma modulators.

Latest Patents

One of his latest patents is a device for synchronizing digital devices. This innovative device includes a local oscillator, an all-digital phase-locked loop, a digital signal generator, sampling circuitry, and an interface. The local oscillator generates a local clock signal, while the all-digital phase-locked loop produces a sampling control signal. The phase detector within the ADPLL generates a phase error signal based on a loop clock signal and a received reference signal. Additionally, the digital filter generates a signal indicative of the frequency ratio between the reference clock signal and the local clock frequency. The sigma-delta modulator then generates a modulated signal based on this frequency ratio, which is used by the sampling circuitry to sample digital signals at a frequency determined by the sampling control signal.

Another significant patent is for a self-calibration circuit for delta-sigma modulators, which includes a quantizer and a signal propagation path with multiple cascaded integrators. In the calibration mode, a digital-to-analog converter receives a periodic alternated digital sequence, allowing the delta-sigma modulator to generate a digital test signal. Calibration circuitry then generates a calibration signal based on this digital test signal and a reference digital word.
