To test products in my R&D lab, I build many universal data-acquisition systems that connect to a PC or another controller through RS-232 links or LANs. These small systems typically include multiple ...

All modern high speed ADCs need an input common mode voltage for their differential inputs that must fall within some acceptable range for correct operation. This is sometimes a trivial issue where ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

How to decide between buffered and un-buffered (switched capacitor), high-speed analog-to-digital converters, with an example of anti-aliasing filter design. The fundamental end goal when using an ADC ...

The V200 input monitor interface connects up to 16 supervised input circuits. Each input point monitors and reports normal, offnormal, and alarm states. The V200 features on-board flash memory, ...

Puff and Suck (or Sip and Puff) systems allow people with little to no arm mobility to more easily interact with computers by using a straw-like unit as an input device. [Ana] tells us that the usual ...
