Session 27 overview - filters and continuous-time ΔΣ converters
R. Roovers, Bill Redman-White · 2005
Achieving the optimum trade-off between the complexity of filtering to restrict analog bandwidth and the dynamic range in the data-conversion function with the lowest power, remains a central issue in many mobile and communication applications. Traditionally, filtering has been used in conjunction with gain control to limit the resolution bandwidth of the ADC, and hence the power consumption, but the partitioning is constantly changing as ADC technology advances.
