For battery-powered circuits, it is easy to build an ultralow-current crystal oscillator designed around a 32.768-kHz crystal. This crystal is common for real-time-clock circuits. Because these ...

Fig 1. This Pierce-series resonant oscillator can reliably start at supply voltages as low as 2.4 V. It also draws very low current, ensuring long battery life. Fig 2. An oscilloscope photo shows the ...

Although oscillators are critical components in most electronic devices, designers needn’t design oscillators themselves in most cases, because the device contains a great deal of the oscillator ...

The 555 timer is one of the most versatile integrated circuits available. It can generate PWM signals, tones, and single-shot pulses. You can even put one in a bi-stable mode similar to a flip flop.

The main goal of the LCP circuit technology development was to provide a high-speed, high-density alternative to conventional printed circuit fabrication techniques. As semiconductor and electronics ...

For reliability, designers must create flex circuits that are neither too thick nor bend too much. • Every flex circuit has a neutral-bend axis. • Smaller circuit thickness reduces the risk of damage ...

• A flexible printed circuit is as much a mechanical device as it is an electrical device. • The neutral bend axis may not be in the exact middle of the material stack. • The reliability of flexible ...

The process of circuit design can cover systems ranging from national power grids all the way down to the individual transistors within an integrated circuit. For simple circuits the design process ...
