Ultrasonic Sensors

7 February 2022 by Phillip JohnstonUltrasonic sensors involve a transmitter that emits a noise (also called a chirp), typically within the 23 kHz-40kHz range, and measure how long the sound wave takes to reflect off of an object and return to a receiver (often placed in close proximity to the transmitter). Using the speed of sound (343m/s at room temperature), the distance to the object can be detected. The simple fact that a is reflected and returns can be used to indicate the presence of an object. Uses Fundamentally, ultrasonic sensors can be used to detect proximity. This is applied …

Linear Voltage Regulator

A voltage regulator that uses a transistor controlled by a negative-feedback circuit to produce a specified output voltage that remains stable despite variations in load current and input voltage.

Wafer-Level Packaging [WLP]

“Wafer-level packaging (WLP) is the technology of packaging an integrated circuit while still part of the wafer, in contrast to the more conventional method of slicing the wafer into individual circuits (dice) and then packaging them.”
