221R950_AD1887JST Introduction

Texas Instruments (TI) today introduced an ultra-low power switching regulator TPS62840, its operating quiescent current (IQ) can reach 60nA, only 1/3 of similar devices in the industry. In addition, the new DC/DC converters have a wide input voltage (VIN) range of 1.8V to 6.5V to support a variety of chemistries and configurations. It delivers very high light-load efficiency of 80% at 1-µA loads, enabling designers to extend the battery life of their systems or use fewer or smaller batteries to shrink their overall power solution size and reduce costs.

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

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

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. Texas Instruments has unveiled what the company calls "breakthrough" bulk acoustic wave (BAW) resonator technology.

. ·Selectable mode can improve performance and reduce overall cost: The selectable mode and stop function of TPS62840 can improve noise performance and reduce signal distortion. These advantages can help reduce solution cost because designers do not need to use more expensive precision signal chain components, sensors or radio solutions to perform the same function to achieve system requirements.

Due to its wide application, analog chips are less affected by a single downstream boom. From the historical data, from 2000 to 2017, the volatility of analog chips was 1.8%, while the volatility of typical cyclical industry memory over the same period was as high as 6.7%.

"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.

In short, advances in BAW technology have brought "higher performance, simpler design, lower cost and smaller size" to wired and wireless networks, Wong explained.

There are also different structures where sound waves propagate as transverse waves. In the above-mentioned BAW-SMR and FBAR?filter diagrams, sound waves propagate in the form of longitudinal waves, that is, the direction of particle vibration and the direction of wave propagation are parallel.

. Time-to-market is accelerated as designers eliminate the need to screen, calibrate and assemble external quartz crystals. TI's new product announcement includes an industry-first crystalless wireless microprocessor (MCU) that integrates a TI BAW resonator in a package. Design engineers can use this MCU to achieve simpler and smaller designs while improving performance and reducing cost.
