Darwin Tolentino and Sandro Herrera, Analog Devices Analog Dialogue Differential signaling finds useful application in circuits where a large signal-to-noise ratio, high immunity to noise, and lower second harmonic distortion are desired, such as ...
Gustavo Castro, Analog Devices Analog Dialogue Question: Why is the effect of common-mode signals at the output larger than the CMRR specification? Answer: The concept of common-mode rejection ratio (CMRR) is fundamental when working with ...
By Moshe Gerstenhaber, Rayal Johnson, and Scott Hunt, Analog Devices Analog Dialogue Introduction Building a voltage measurement system with nanovolt sensitivity presents many design challenges. The best available op amps, such as the ultralow ...
By Qui Luu, Analog Devices Analog Dialogue Part 1 Analysis The plots provide invaluable data on the supply sensitivities at each power pin. VPOS_PLL has the worst power-supply rejection and is therefore the most sensitive power node. This power pin ...
By Qui Luu, Analog Devices Analog Dialogue As more building blocks are added to a radio-frequency integrated circuit (RFIC), more sources of noise coupling arise, making power management increasingly important. This article describes how ...
Alan Walsh, Analog Devices EDN A common issue that arises when designing an ADC circuit is how to protect the ADC inputs from over voltage. Protection of ADC inputs have many scenarios and potential solutions. ADCs from all vendors have similar ...
Umesh Jayamohan, Analog Devices Analog Dialogue Introduction The design of the input, or front end, of any high-performance analog-to-digital converter (ADC), especially an RF-sampling ADC, is critical to achieving the desired system-level ...
David Hunter, Analog Devices Analog Dialogue Part 1. The AD8338 Input Network For this design, the differential output amplitude will be 1.0 V. With factory default settings, the internal 500 Ω resistors, and maximum gain, the input amplitude ...
David Hunter, Analog Devices Analog Dialogue In the past, the most difficult part of an arbitrary waveform generator was designing the output stage. Typical signal generators offer output ranges from 25 mV to 5 V. To drive a 50-Ω load, ...
Steven Xie, Analog Devices Analog Dialogue Introduction Successive-approximation analog-to-digital converters, called SAR ADCs due to their successive-approximation register, are popular for applications requiring up to 18-bit resolution at up to 5 ...
