1.65V Low Noise Microphone Bias for Microcontroller Business in TSMC 55nm

MICBIAS is a low noise microphone-bias-voltage generator that provides 1.65V regulated output.

Overview

MICBIAS is a low noise microphone-bias-voltage generator that provides 1.65V highly regulated output. The output voltage can be programmed with 6 trimming Bits for ?+/-75mV range. The bias-voltage generator has low output noise of 3.5uVRMS across the audio range frequency. It has typical PSRR of 80dB across audio range.

The external mode operation gives option to bypass the MICBIAS output to provide with customized bias-voltage.

Audio Validation in Multimedia Systems and its Parameters

In the massive world of multimedia, sound stands as a vital component that adds depth to the overall encounter. Whether it's streaming services, video games, or virtual reality, sound holds a crucial role in crafting immersive and captivating content.

Using audio codecs IP as the digital audio hub in mobile multimedia systems

By integrating an audio analog codec that implements the 'audio hub' functionality and is able to process and mix audio signals from asynchronous sources, system designers can free the scarce main processor resources for more relevant tasks and simplify the system design, thus achieving a more effective solution.

Application Hardware Modeling: Selective modeling for early prediction of subsystem performances through simulation

The virtual validation of subsystem performances (Pop-up Noise, Signal-to-Noise Ratio, Power supply Noise, Power consumption...) requires the modeling and simulation of complete subsystems. Application Hardware Modeling (AHM) consists in addressing the risks of performance degradation while integrating a Silicon IP in its Integrated Circuit (IC) and this IC on its Printed Circuit Board (PCB). The selection of relevant models for a subsystem performance, along with the creation and validation of models through equivalence checking, are the basics of Application Hardware Modeling for right-on-first-pass subsystems!
