In a cell phone it's important to set the power level of a power amplifier (PA) precisely. This is necessary to compensate for the temperature variation and to set the correct power, which is dictated by the base station. A well-established method to set the power level precisely is closed loop power control. It measures the PA output power and adjusts the power level depending on the measurement. In this article, a National Semiconductor engineer offers the theory of operation for a built-in po

Electronics integration continues to reduce camera form-factor and cost though a clear partitioning of digital and analog functions suggests little technical or economic benefit from combining disparate functions into a common IC process. Sometimes the road less-integrated provides an optimum balance of function, design risk, and cost, particularly when it comes to mixed-signal systems, writes David Carey in this installment of Under The Hood " Analog Edition. That doesn't mean there isn't a lot

Electronic design has changed considerably since the days when TTL and 5V CMOS were the dominant standards for logic circuits. The increasing complexity of modern electronic systems has led to lower-voltage logic, which in turn causes incompatible input and output levels for the logic families within a system. It's not unusual, for example, that a digital section operating at 1.8V must communicate with an analog subsection operating at 3.3V. In this article from Planet Analog magazine, a Maxim e
