Why VAD and what solution to choose?

More than ever before, the attention to power consumption is paramount when developing new products. In this environment, voice activity detection has a major role to play for any new voice-controlled system.

Improving Battery-Powered Device Operation Time Thanks To Power Efficient Sleep Mode

Allowing battery-powered devices to run, without battery recharge, for years rather than months, partakes in enhancing significantly end-user satisfaction and is a key point to enabling the emergence of IoT applications. Numerous applications, such as M2M, BLE, Zigbee…, have an activity rate (duty cycle) such that the power consumption in sleep mode dominates the overall current drawn by the SoC (System on Chip). For such applications, the design of the “Always-On power domain" (a.k.a AON power domain) is pivotal.

Pairing Sensitive RF with Voltage Regulators for Noise-Free IoT Modules

This article presents the challenge of pairing an RF analog circuit with the appropriate inductor-based embedded Switching Regulator (namely eSR, equivalent to on-board DC/DC) allowing to meet both the power efficiency requirements and the module performance level at the same time.
