ACU2109_AD1896AYRSZ Introduction

The low IQ of the TPS62840 enables 80% efficiency at 1-µA loads, 30% higher than comparable devices in the industry. . Longer battery life and very high light load efficiency: Lower IQ consumption provides longer IQ for very light loads (below 100µA) and systems operating primarily in standby/factory mode (no switching) battery life.

. 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.

The basic structure of the BAW filter is that two metal electrodes sandwich a piezoelectric film (the thickness of the Quartz substrate is 2um at 2GHz), and the acoustic wave oscillates in the piezoelectric film to form a standing wave.

The F2838x microcontrollers integrate three industrial communication protocols, enabling designers to tailor a microcontroller to the specific needs of each system. A key component required to achieve this is a new connection manager based on the Arm® Cortex®-M4 subsystem, which reduces some of the processing-intensive communications and optimizes connectivity.

Ray Upton, TI's vice president of connected microcontrollers, explained that new technologies are critical to "moving large amounts of data in a stable manner," improving high-performance communications. .

In addition to these features, the C2000 F2838x microcontrollers offer enhanced real-time control performance and greater flexibility than previous generation C2000 series microcontrollers. For more information on the F2838x family of microcontrollers, .

The overall effect of this structure is equivalent to contact with air, and most of the sound waves are reflected back. This structure is called BAW-SMR (Solidly Mounted Resonator), as shown below. One way is to form a Bragg reflector under the oscillating structure to reflect sound waves into the piezoelectric layer. The reflector consists of several layers of alternating high and low impedance layers. For example, one layer has a large acoustic wave impedance, the second layer has a small acoustic wave impedance, and the third layer has a large acoustic wave impedance, and the thickness of each layer is λ/4 of the acoustic wave, so that most waves will The reflected back and the original wave are superimposed.

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.

TI's new newer SimpleLink™ multi-standard MCUs with ?BAW technology can be integrated into low-power wireless RF devices, such as low-power crystalless Bluetooth and Zigbee? technology, thereby reducing wireless RF failures caused by external crystals.

Physically, waves are mainly divided into two types, one is electromagnetic wave, which does not require any medium, but propagates through the periodic oscillation of the electric and magnetic fields generated by the initially charged particles. It can also propagate in a vacuum. Radio waves, microwaves, visible light, X-rays, and gamma rays are all electromagnetic waves.
