It is reported that Renesas expects to close two more 150mm fabs in 2020 or 2021. Taking Renesas as an example, the company's two recently closed fabs are both 150mm, including a factory in Kochi Prefecture, Japan, which mainly produces analog, logic devices and some old-fashioned micro components. In addition, Renesas has adjusted its factory in Otsu, Shiga Prefecture, Japan, to manufacture optoelectronic devices. From a regional perspective, Japan closed a large number of fabs.

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. In April 2019, Texas Instruments released the construction plan for this 300mm fab, with an estimated investment of 3.1 billion mei yuan.

The beautiful imagination for applications in various vertical industries derived from this is like a science fiction novel, and the premise that supports the realization of this novel is a towering base station that does not look so romantic.

TI's chargers help reduce power consumption through heat dissipation, allowing video doorbells to last longer with their batteries. . For example, video doorbells that normally rely on AC power to operate can be guaranteed when the main power source is switched to a battery pack.

The reduction in component count is valuable for applications such as smart speakers; and as market adoption increases, the size and cost of these applications continue to shrink. Switching metal-oxide-semiconductor field-effect transistors (MOSFETs), charge path management FETs, input current and charge current sensing circuits, and dual input select drivers.

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

. The resonator used in the Ladder type (SAW is also mentioned later) includes series and parallel. A series resonator plus a parallel resonator is called a stage, and the entire ladder type filter can be composed of several stages.
