Fundamentals of Analog/RF design: Noise, Signal, Power

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 […]

Analog vs Digital – Part 3: Digital

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, […]

Analog vs Digital – Part 1: Introduction

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 don’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 […]
