Pay Attention To Switch Arrangement To Improve PGA Performance
Programmable-gain amplifiers (PGAs) are often used in communication systems, such as basestations. Designers can select fully integrated, single-IC PGAs, which are now available with bandwidths over 500 MHz. But obtaining the low second- and third-order distortion that is critical in communication applications isn't easily achieved. Combine that with the desire for greater choice in the attenuation level and step size, and designers may opt to construct a PGA using a...
