Basics of Tunnel Diodes and their applications

by w2aew @ youtube.com:

Tunnel diodes are a bit rare these days, but still have uses in special applications including extremely high frequency oscillators, etc. They were commonly used in microwave circuits, oscilloscope trigger circuits, and other applications. This video reviews the basics of tunnel diodes, including the basic properties and simple applications. I refer to these as the “bucking bronco” of diodes because of the IV curve that jumps around, and the fact that these diode will jump into wild oscillation if you just look at them funny!

In this episode Shahriar explores the world of Delta-Sigma modulators with emphasis on a Delta-Sigma Analog to Digital Converter (ADC). The basic concepts of analog to digital conversion is presented, particularly with respect to quantization noise spectral shape and power density. Next, oversampling ADCs are presented to demonstrate the possibility of increasing SQNR (ENOB) through manipulation of quantization noise spectrum.

Due to the practical limitations of high oversampling ratios, delta-sigma modulations is explored. The principle operation behind delta-sigma ADCs is presented with detailed explanation on noise shaping, filtering and decimation. The signal and noise transfer functions for a 1st order and 2nd order delta-sigma ADC are derived. Finally, as a practical example, a 2nd order delta-sigma ADC based on a 1-bit quantizer is presented. The ADC uses two Miller integrator op-amps, one comparator and a D-Type flip-flop. The complete measurement of this delta-sigma ADC is presented. The impact of over sampling ration, op-amp linearity and input signal bandwidth is presented. The slides for this video can be downloaded from The Signal Path website.

It’s been a busy year for element14 and the online social community for engineers is ending 2011 on a high note with the launch of element14 TV, the industry’s first online television channel designed for electronics engineers and tech enthusiasts.

The new dedicated channel offers instant access to an expansive range of information-rich content in one, easy-to-search destination.  Anchored by The Ben Heck Show, a leading online TV tech series, this “YouTube for engineers” offers a programming line-up spanning electronics how-tos, Arduino tutorials, user-generated videos, informational videos from leading electronics component and subsystem providers, and the latest in technology and product overviews.

If your schedule permits, we’d love to get you on the phone with Diane Kibbey – global head of the community – to talk about the new channel, the growth of the community over the past year and exciting plans for video down the road.
