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 ...

Linear actuators and oscillating systems constitute a vibrant area of research that bridges concepts in electromagnetism, mechanics and control engineering. These systems convert various forms of ...

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 ...

Editor’s Note: This DI is a two-part series. Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher ...

Update: These are likely an iPhone 5 clone (with better vibrating motor). Note the smaller 1150 mAh battery and the (d’oh) SD card slot. The images above allegedly show a Foxconn assembly line in ...

The LTC6902 from Linear Technology is a precision, easy-to-use, resistor programmable oscillator that provides up to four output phases. Its frequency can be varied from 5 kHz to 20 MHz, with 1.5% ...

According to the latest rumblings out of East Asia, Apple's next iPhone will come with an advanced vibration unit that can provide varying levels of haptic feedback in specific areas of the handset's ...
