Filters and Amplifiers
JoAnn Close, Vadim Gutnik · 2008
Configurability and calibration are central topics in research on amplifiers and filters. Calibration is often required to compensate for variations in silicon performance so that product yields are acceptable. Configurability also enables system integration in sensors and transceivers which operate in multiple modes and with multiple data rates, particularly in the case of software-defined radios. The ability to tune and configure analog blocks comes at a price however; calibration can be expensive and the overhead required for configurability can degrade performance. The circuits presented in this session demonstrate a variety of approaches to calibration and to allow flexible configurations without steep performance penalties.
