AD1851R_AD3000A-ADJ 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.

In the analog chip market, manufacturers like TI, ADI, and Maxim all have gross profit margins higher than the industry average. The data shows that TI's analog chips had an operating profit margin of 46.7% in 2018, but the operating profit margin of embedded processors was only 29.6%. Take TI as an example, its profits and profit margins have maintained an upward trend over the past 10 years and reached new highs in 2018. According to TI, creating high profit margins is related to their use of 12-inch fabs to produce analog chips and reduce costs.

Hyundai Motor Corporation's RANC system significantly reduces noise in the vehicle cabin. The system can analyze all kinds of noise in real time and generate anti-phase sound waves. This new technology can deal with a variety of different road noises, such as the resonance between the tire and the wheel, or the roar from the road surface.

Currently, the deployment of such automotive road noise reduction systems requires a cost-effective low-latency network technology that can efficiently connect the required input sensors to the central processing unit.

Taking TWS (true wireless Bluetooth headset) as an example, the active noise reduction function has also become a "just-needed" function for product market competition. "Sophie, Marketing Manager of Industrial and Medical Consumer Products of ADI's China Business Unit, said in a recent interview. "Faced with the increasingly strong demand for active noise reduction for the next generation of TWS headphones, how can upstream manufacturers provide high-performance chips and algorithm solutions to help Importing products to customers and quickly bringing them to the market is the key for TWS earphones to seize market opportunities in the 'second half' competition. .

In the Airgap type, an auxiliary layer (sacrificial support layer) is deposited before the piezoelectric layer is formed, and then the auxiliary layer is removed to form an air gap under the oscillating structure. ?? Because only the edge part is in contact with the underlying substrate, this structure is relatively fragile when under pressure, and similar to the membrane type, the heat dissipation problem also needs attention.

As a common piezoelectric material, quartz exhibits a linear response under high voltage and high pressure, but there is no suitable method to make quartz into a thin film deposit on a Si substrate. Appropriate BAW piezoelectric materials require high electromechanical coupling coefficient, low electromechanical loss, high thermal stability, and conform to IC process technology.
