Everything should be made as simple as possible, but no simpler.
Albert Einstein (1879–1955)
As the most common approach for realizing accurate and linear analog signal pro-
cessing (ASP) in metal-oxide semiconductor (MOS) integrated technologies,
switched-capacitor (SC) circuit techniques have dominated the design of high-quality
monolithic fi lters since the 1980s. The incomparable technological adaptability shown
by SC circuits has furthermore made them the competent candidate appropriate for a
rich variety of applications such as instrumentations, digital audio, wireless communi-
cations, power management, and sensors. This near ubiquity is perhaps the aspect of
SC circuits that intrigues circuit designers and engineering students the mos ...
