Various implementations of transimpedance amplifiers (TIAs) are used for current sensing applications and they allow for low noise and wide bandwidth (BW). The process of digitization is usually not implicitly discussed. Though, BW limitation, sampling and quantization obviously add additional circuit complexity and have a strong influence on the minimum achievable spot-noise in low noise TIAs. We introduce a mixed-signal topology for the integrator-differentiator TIA (I-D-TIA), which introduces the analog-to-digital converter (ADC) before differentiation, thereby avoiding the implementation of the usually wideband and power-dominating analog differentiator. The proposed topologies are compared by circuit-level simulations.

The technical evolution that continues through 2015 and beyond has been coming for a time, but only in the past few years have studies identified three key indicators driving that [...]

For electronic product design, smaller is better. From the latest mobile phone to personal digital assistants, the consumer electronics market is focused on cramming more functionality into ever-smaller spaces. The […]

It makes perfect sense once it's broken down Until recently, electronic products such as computers and cellular telephones have been designed by a relatively small group of designers using a [...]

I was thinking that an organization like IMBA should be educating new riders and re-educating seasoned riders about trail etiquette by simply including an information card or pamphlet with every new mountain bike purchase. As for a lot of riders, the "mountain bike riders" as you refer to them, I think they do not know any better. A long time ago, when customers would buy a bike, they would often get a card included with their bike from IMBA explaining what the organization was and why it was important.
