This two-transistor white noise generator has a surprising feature about 30dB more noise than the more traditional designs. Q1 and Q2 can be any small-signal transistors with a beta of up to 400. The reverse-biased emitter-base junction of Q1 provides the noise source, which is fed into the base of Q2. Q2 forms a simple amplifier with a gain of 45dB. The improved output level is due mainly to the inclusion of C1, which provides a low-impedance AC source to the noise source while not disturbing t.......

Many years ago National Semiconductor came out with a neat white noise generator IC. They are no longer being made but they can still be found on eBay. This little 8 pin part is very easy to use. It draws about 4ma of current and can operate over a range of 4.5v to 11.5v.

by Travis Goodspeed with kind thanks to Sergey Bratus, Ryan Speers, and Ricky Melgares, for contributions of code, conversation, and general neighborliness. As I was recently reminded that the Crossbow Telos B and Sentilla TMote Sky devices litter most universities, left over from wireless sensor network research, it seemed like a perfect target. As such, I'm happy to announ.......

Linear Technology has a very broad line of LED driver ICs for automotive, display backlighting, handheld and general lighting applications. They are configured as either Inductorless white LED drivers (for LEDs in parallel), or switching regulator based white LED drivers (for LEDs in series). Topologies include boost regulator LED drivers, buck regulator LED drivers, buck-boost LED drivers, SEPIC topology led drivers and more. Regardless of topology, these LED driver ICs offer the highest effici.......

Piezoelectric sensors measure changes in pressure, acceleration, temperature, strain or force and are used in a vast array of devices important to everyday life. However, these sensors often can be limited by the ??white noise ? they detect that can give engineers and health care workers false readings. Now, a University of Missouri College of Engineering research team has developed methods to enhance piezoelectric sensing capabilities. Enhanced sensors could be used to improve aviation, detec.......

APPLICATION NOTE AN1026 1/f Noise Characteristics Influencing Phase Noise Abstract In applications such as VCO"s where 1/f noise is one of the major contributors to phase noise, the device with the best 1/f noise will yield the best phase noise. To better understand how 1/f noise changes with bias and from device to device, the.......
