本連載の初回の記事 1 では、フィルタの位相と実装トポロジーの関係について考察しました。それに続き、前回は 2 は、ローパス応答とハイパス応答に注目し、フィルタの伝達関数における ...

The EVAL-LT3074-AZ evaluation board features the LT3074, a 3A, ultralow noise, high power-supply rejection ratio (PSRR), 45mV dropout ultrafast linear regulator with PMBus capability. The input ...

Op amps are very high gain amplifiers with differential inputs and single-ended outputs. They are often used in high precision analog circuits, so it is important to measure their performance ...

Today’s electronic systems are becoming more and more complex, with an increasing number of power rails and supplies. To achieve optimum power solution density, reliability and cost, often system ...

Comparator ICs are designed to compare the voltages that appear at their inputs and to output a voltage representing the sign of the net difference between them. In a comparator circuit, if the ...

Q. I've just been reading datasheets of some recently released Analog Devices log amps and I'm still a little confused about what exactly a log amp does. A. You're not alone. Over the years, I have ...

Although it is advantageous to implement op-amp circuits with balanced dual supplies, there are many practical applications where, for energy conservation or other reasons, single-supply operation is ...

Serial peripheral interface (SPI) is one of the most widely used interfaces between microcontroller and peripheral ICs such as sensors, ADCs, DACs, shift registers, SRAM, and others. This article ...

An effective method for filtering high frequency power supply noise and cleanly sharing similar voltage supply rails (that is, analog and digital rails for mixed-signal ICs) while preserving high ...

The thermocouple is a simple, widely used component for measuring temperature. This article provides a basic overview of thermocouples, describes common challenges encountered when designing with them ...

The EE-Sim DC-to-DC converter tool uses your requirements to quickly create a complete power design including a schematic, BOM with commercially available parts, and time and frequency domain ...

When designing a DC-to-DC converter, components such as FETs, inductors, current sense resistors, and output capacitors are carefully selected to match desired output voltage ripple and transient ...
