Title: Giovanni Gonano: Innovator in Electronic Apparatus and Audio Technology

Introduction

Giovanni Gonano is a prominent inventor based in Padua, Italy, known for his significant contributions to electronic apparatus and audio technology. With a total of 14 patents to his name, Gonano has made remarkable advancements in the field, particularly in the areas of switching-type output stages and digital audio playback circuits.

Latest Patents

One of his latest patents is titled "Electronic apparatus comprising a switching-type output stage, corresponding circuit arrangement and method." This invention features an embodiment apparatus that includes a switching-type output power stage and a modulator circuit designed for pulse-width modulation. The modulator converts an electrical input signal into a pulsed signal, ensuring that the mean value is proportional to the amplitude of the input signal. Additionally, the circuit arrangement controls the saturation of the output signal supplied by the switching-type output power stage. A notable component of this invention is the pulse-remodulator circuit, which enhances the performance of the switching-type output power stage by remodulating the pulsed input signal when necessary.

Another significant patent by Gonano is the "Noise shaper fader." This digital audio playback circuit incorporates a noise shaping circuit that processes an input digital audio signal. It features a digital to analog converter (DAC) that transforms the digital signal into a pre-amplified output analog audio signal. The circuit also includes a muting mechanism that compares the input signal to a threshold, asserting a mute control signal when the input falls below this threshold. The analog gain control ramp circuit generates a gain control signal in response to the mute control signal, allowing for a smooth ramp down of the gain.
