This Design Idea avoids the RC charging waveshape of a standard relaxation oscillator, replacing it with a linear rise/fall triangle wave. Positive feedback is used to increase the charging rate over ...

Apple used a linear oscillating vibrator with the iPhone 4S, as pictured in this teardown image. iFixit noted the change was a “head-scratcher”: ...

Labeled as a "secret weapon," the system is said to be driven by a linear oscillating motor, much like the unit found in the iPhone 4S.

Linear Technology has released a set of simple small timing ICs, including: a voltage-controlled oscillator, a low frequency oscillator, four pulse width modulated oscillators, four monostable pulse ...
