Abstract: This paper discusses the successful implementation of two reference circuits tailored to the space-saving needs of ultrasound imaging applications, which commonly encounter the demand for one reference source to power multiple...

Abstract: Semiconductor topic: Many linear and switched-mode power supplies and voltage regulators use a resistor network as feedback into the regulator to adjust the voltage output. This is typically done either by varying the values o...

Abstract: This article provides an in depth analysis, procedure, and selection tables for selecting the optimum series voltage reference for voltage output DACs. It covers all of the important parameters such as: input supply voltage, r...

Whether squeezing the last millijoule from your battery or operating a cooler CPU board, the goal is to burn less power. For many loads the power dissipation varies as the square of the applied voltage, so one approach is simply to minimiz...

A data acquisition board, in order to provide flexibility, must be able to accommodate various input voltage ranges. Handling low amplitude signals generally requires an increase in the number of bits of resolution, increasing cost....

P-channel MOSFETs (P-FETs), though more expensive than pnp transistors, are free of the dissipation loss associated with base drive in a pnp circuit. P-FETs also have a lower saturation voltage at light loads (Figure 1). In fact, th...
