The benefits of differential circuits

By Poojan Wagh | Published: June 11, 2009
Introduction From my personal blog: I’ve been lucky enough to find myself in a team that’s intent on finding the best circuit design for a given application. This doesn’t happen often to many people, but I feel that I’ve had more than my share of this opportunity. The conclusion is usually that we come up with some topology [...]

Circuit Simulator Analyses

By Poojan Wagh | Published: November 13, 2008
I’ve decided to go through some basics of circuit design. In this post, I’ll cover the different types of circuit simulator analyses. Most are available in SPICE, Synopsys HSPICE, Cadence Spectre, and Agilent ADS, depending on vendor-specific options.

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

By Poojan Wagh | Published: November 5, 2008
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 [...]
