Title: Paolo Cacciagrano: Innovator in Digital Audio Technology
Introduction
Paolo Cacciagrano is a notable inventor based in Cairate, Italy. He has made significant contributions to the field of digital audio technology, holding a total of 3 patents. His work focuses on enhancing audio playback systems through innovative circuit designs.
Latest Patents
One of his latest patents is the "Noise Shaper Fader." This invention involves a digital audio playback circuit that includes a noise shaping circuit designed to receive an input digital audio signal. It features a digital to analog converter (DAC) that converts the input signal into a pre-amplified output analog audio signal, following a gain ramp defined by a gain control signal. Additionally, a muting circuit compares the input digital audio signal to a threshold, asserting a mute control signal when the signal falls below this threshold. An analog gain control ramp circuit generates the gain control signal in response to the mute control signal, allowing the gain ramp to decrease. An amplifier then amplifies the pre-amplified output analog audio signal for playback by an audio device.
Another significant patent is for an "Electronic Converter, Related Audio System, Integrated Circuit and Method of Operating an Electronic Converter." This invention includes a series of switches and an inductor that work together to regulate voltage during charge and discharge phases. The control circuit monitors the regulated voltage between output terminals, ensuring efficient operation of the converter.
