In the current digital age, electronic devices are becoming increasingly more critical, especially mobile devices and "always-listening" devices such as virtual personal assistants. To gather data from the real world, which in this case is voice audio, digital devices need to convert the analog input signals captured by a microphone to a digital stream. The process of data conversion is usually an energy expensive process, where lower power drawing implementations would benefit battery powered devices and provide less energy consuming "always-listening" devices. One of the most appealing Analog to Digital Converter (ADC) implementations are done using Sigma-Delta Modulators ( Ms) due to their use of oversampling that allows the no...
