Analog Diablog is the place to comment on the articles found in Analog Dialogue (or those that you'd like to see). It can also be used as a discussion forum on products, applications, technology, and techniques for analog, digital, and mixed-signal processing using Analog Devices components.
Modern digital radio transmitter design poses increasing challenges for equipment designers. The trend towards greater data throughput is increasing the modulation density and carrier bandwidth of transmitted signals. To maintain good adjacent channel power ratio (ACPR) without increasing the rms power level, components with lower intermodulation distortion and lower noise must be used.
ESD diodes can be used to accurately measure the junction temperature of a high-speed amplifier. This article shows how, and compares this measurement with estimates obtained from the thermal specifications found on the data sheet.
It is often desirable to measure the performance of a feedback network in a particular configuration so as to model the open-loop behavior. But this type of measurement is often challenging due to high gains, small input signals, and long settling times. This article shows you how to characterize the frequency response of the network rapidly and with minimal effort, using available tools and a small amount of special circuitry.
