Next generation high-speed sigma-delta ADC architectures
June 13, 2012 // By Maury Wood, Heribert Geib, Lucien Breems and Muhammed Bolatkale
A promising architecture for next generation high-speed Analog to Digital Converters (ADCs) is the so-called sigma-delta (ΣΔ) converter architecture.
NXP Semiconductors has contributed to sigma-delta converter research and development since 1952, when the paper “Delta Modulation, a Method of PCM
Transmission Using the One Unit Code” appeared in the Philips Research Report.
The first commercial sigma-delta (or delta-sigma) data converters were introduced to the market in the early to mid-1990s. They were a huge success, for a number of reasons. They almost entirely eliminated the external analog anti-aliasing and anti-image filters required by legacy Nyquist converters. This significantly reduced the Bill of Materials (BOM) costs, and improved system phase linearity. And unlike their predecessors, the new sigma-delta converters did not require the laser trimming of resistor ladders, thereby significantly reducing both die and test manufacturing costs.
