The quartz crystals prevalent in cell phones and PCs work with currents that max out at 1 µA. With such a small full-scale current range, a tiny error in the current a circuit sends through the crystal can result in a terribly inaccurate clock.; cell phones; computer clocks; jim williams; linear technology; nanoamps; quartz crystals; video design idea; Mark Thoren, mixed-signal application engineering manager with Linear Technology, demonstrates an amplifier-based circuit design for a relatively inexpensive precision voltage source.; Mark Thoren; amplifier-based circuit design; linear technology; mixed-signal application; precision voltage source; In this Tech Clip, Howard Johnson shows an animation that illustrates the form of signal degradation you will experience as the length of a PCB trace increases. ; Signal Consulting; Signal dispersion; high-speed signals; howard johnson videos; In this Tech Clip, Howard Johnson illustrates the reflections generated by that parasitic effect, and the attenuation of fast pulses that it causes.
