In April 2019, Texas Instruments released the construction plan for this 300mm fab, with an estimated investment of $3.1 billion. However, in view of the sluggish semiconductor market in 2019 and the unsatisfactory revenue situation, TI's plan to invest in the construction of a 300mm wafer fab in Richardson is not as smooth as originally expected, and it may be delayed for two years to complete.

. With the maturity and progress of the process technology and the increase in market demand, more and more companies use advanced processes below 20nm to design and produce ICs and devices, which makes more and more IDMs and foundries eliminate low-efficiency production. fab.

In this case, BAW resonator technology offers TI a huge advantage by eliminating the need for external components mounted on the PCB. "Everyone uses quartz crystals for clocks," Solis said. Today, timing often requires a quartz crystal.

In order to gain an in-depth understanding of TI's new breakthrough in BAW technology, let's start with the principle of BAW filter: . For the first time in the industry, TI uses this technology for integrated clock functions. • In the past, BAW resonator technology has been used to filter signals in communication technologies such as smartphones.

We are passionate about reducing the cost of electronics and making the world a better place through semiconductor technology. Today, each generation of innovation builds on the previous generation, making our technology smaller, more efficient, more reliable, and more affordable - opening up new markets and enabling semiconductors to be widely used in electronics, This is the advancement of engineering. This is exactly what we have been doing for decades and now.

Thanks to these features and its selectable functions, the TPS62840 helps engineers overcome key design challenges in many battery-operated, continuous-run industrial and personal electronics applications, including narrowband IoT, grid infrastructure equipment, and renewable energy. Wearables, they all require greater flexibility and precision, wider wireless range, and reduced electromagnetic interference (EMI).

. On the other side of the oscillating structure, the acoustic impedance of the piezoelectric material is not much different from that of other substrates (such as Si), so the piezoelectric layer cannot be deposited directly on the Si substrate. In order to keep the acoustic wave in the piezoelectric film to oscillate, there must be sufficient isolation between the oscillating structure and the external environment to obtain a small loss and a large Q value. The propagation speed of sound waves in solids is ~5000m/s, which means that the acoustic impedance of solids is about 105 times that of air, so 99.995% of the sound wave energy will be reflected back at the boundary between the solid and the air, which is the same as the original wave (incident wave). together to form a standing wave.

The technology, which also enables high-precision and robust communication between IoT devices, can now be developed in a less bulky form, said Kim Wong, vice president of high-speed data and clocking at TI.

Ladder type can be used on single-ended (single-ended/unbalanced) and differential (balanced) signals, while lattice type is more suitable for differential (balanced) signals.

There are many types of BAW filters, including ladder type filter, lattice type filter, stacked crystal filter and coupled resonator filter. The BAW filter can connect multiple resonators according to a certain topology. Only the ladder type and lattice type are briefly introduced here.
