Bluetooth’s wideband voice calls differ from narrowband voice primarily in the sampling rate, which increases from 8k to 16k, and the codec changes from CVSD to mSBC (modified SBC). The HFP (Hands-Free Profile) related to Bluetooth voice calls strongly recommends using a packet loss concealment (PLC) algorithm during wideband voice calls to ensure voice quality … Read more
In the current era of rapid growth in the global digital economy, the semiconductor industry, as the cornerstone of modern technology, plays an increasingly prominent supporting role. The strong demand for semiconductors in fields such as the Internet of Things and artificial intelligence is driving continuous expansion of the industry scale. Advances in semiconductor technology, … Read more
In semiconductor fabs, the PVD, CVD, and CMP modules are collectively referred to as the thin film department. Following this convention, I will discuss these three types of equipment together. From the name thin film, it is clear that these three types of equipment are used for the deposition of thin films and for the … Read more

With the rapid development of wearable electronic devices, thermoelectric technology has gained attention for its ability to convert low-grade thermal energy from the human body or the environment into electrical energy. Traditional electronic thermoelectric materials (such as inorganic semiconductors and conductive polymers) are limited by low thermoelectric potentials (usually below 10 µV K⁻¹) and rigid … Read more
