噪声重要与否，取决于它对目标电路工作的影响程度。 例如，一个开关电源在3 MHz时具有显著的输出电压纹波，如果它为之供电的电路仅有几Hz的带宽，如温度传感器等，则该纹波可能不会产生 ...
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 ...
Tata Group, a global enterprise headquartered in India, and Analog Devices, Inc. (Nasdaq: ADI), a global semiconductor leader, today announced a strategic alliance to explore potential cooperative ...
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 ...
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 ...
The difference between insignificant noise and significant noise is the degree to which the noise affects the operation of the circuit in question. For example, a switching power supply has a ...
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 ...
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 ...
Even with the widespread use of rail-to-rail single supply op amps, there is still often the requirement for dual rails (for example, ±15 V) to be generated from a single (positive) input power rail ...
Although current mirrors and circuits such as the Howland current source are taught in analog circuit courses, a surprising number of engineers tend to think exclusively in terms of voltage when ...
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 ...
