.. range. (Detailed analysis of ac performance goes far beyond the scope of this article. I would recommend using Spice simulation for the practical design). The circuit could employ a variety of rail-to-rail micropower op amps for ...
In 1986, famed analog innovator Jim Williams, in “Designs for High Performance Voltage-to-Frequency Converters” ( Reference 1 ) published his 100 MHz “King Kong” VFC. If anyone’s ever done a faster VFC, I haven’t ...
Battery stack voltage monitor development ( Reference 1 ) is aided by a floating, variable potential battery simulator. This capability permits monitor accuracy verification over a wide range of battery voltage. The floating battery simulator is ...
.. the new product and conversion board are available for purchase through online distributors. In addition, the high accuracy SPICE model called ROHM Real Model is available on ROHM’s website for verification simulations. ...
Editor’s note:Battery charging in a float or maintenance mode has been around for a while, especially for standby power, emergency lighting, telecom, uninterruptible power, and other critical power needs. The float method of charging is a ...
High speed and precision are not the only areas where special V-F circuits are needed. Figure 1 shows a circuit which runs from a single 1.5 V cell with only 125 µA current drain. The circuit uses an LT1017 dual micropower comparator in a ...
The gain temperature coefficient of conventional V-F circuits is affected by drift in the charge pumping capacitors. Although compensation schemes are employed to minimize the effect of this drift, another approach is required to get significantly ...
