Analog design does not scale the way digital design does. Namely, as process shrinks, one does not immediately benefit by having reduced power consumption for the same performance. I will show in this post the main constraint involved in analog/RF design: that to maintain a given SNR, a certain amount of power must be consumed […]

However, here’s how I compute SNR/SNDR from an FFT using Cadence Ocean/Skill.
In part 2, I defined the analog signal and the analog gadget. In this post, I give a definition for a digital signal/gadget with examples. signal: a digital signal occurs as a sequence of values gadget: a digital gadget processes information sequentially From this definition, very few things that one encounters are intrinsically digital. Nonetheless, […]
In part 1, I defined the terms signal and gadget. In this post, I give a definition for an analog signal/gadget with an example. signal: an analog signal is a signal that always has a value. They key term is always. gadget: an analog gadget operates continuously on an analog signal. By this definition, everything […]
The last 20 years have greatly improved the feature set and portability of electronics and anything which does or can contain electronics. Nonetheless, most people donâ€™t know what the word digital means. In this multi-part series, I will explain the difference between digital and analog, why digital processing is better than analog, and why some […]
