Also, for analog use, the ROI of a 300mm fab is likely to be higher because it can last 20 to 30 years. TI has been steadily ramping up its production of analog chips on 300mm wafers in recent years to cut costs and increase productivity. TI said the 300mm fab yields 40% cheaper chips than the 200mm process used by competitors.

Another product announced by TI is a network synchronizer based on BAW technology that works with a quartz crystal to reduce digital noise or jitter. Noise cancellation will bring many advantages to telecom systems such as 5G networks. These noise and jitter typically come from the input signals of the communications subsystems of the wired or wireless hardware infrastructure in the data center core network.

"Quartz crystals require additional components to extend their accuracy -- over time -- as their performance changes beyond controllable temperature changes," he added. In addition, Solis said, "using a BAW resonator is more efficient than using a quartz crystal. precise.

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.

Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology. This enables TI to introduce the industry's first crystalless wireless MCU for the embedded market, the SimpleLink CC2652RB, with the clock contained in the same chip. At just 100 microns in size, these tiny timers are smaller than the diameter of a human hair, but they operate at much higher frequencies than quartz crystals, enabling the integration of high-precision and ultra-low jitter clocks directly into packages that contain other circuitry, TI say.

"The new BAW resonator technology is important because TI is integrating it into its silicon products, reducing design time, solution size and component cost," said Philip Solis, research director for connectivity and smartphone semiconductors at IDC.

The typical basic structure is shown in the figure (a) above, with the piezoelectric layer sandwiched between the upper and lower metal electrodes, the corresponding mBVD equivalent circuit is shown in the figure (b) above, and the corresponding impedance is shown in the figure (c) above. It can be seen that there are two resonance frequencies, series (fs) and parallel (fp). The working principle is as shown below.

Compared with BAW-SMR, a smaller part of the membrane type is in contact with the underlying substrate, which is not easy to dissipate heat. However, the thin film structure needs to be strong enough to be unaffected by subsequent processes.
