Analog-to-Digital and Digital-to-Analog Converters,This chapter provides a theoretical review on analog-to-digital converters (ADCs) and digital-to-analog converters (DACs). An in-depth study of signal processing operations including sampling, quantization, requantization, and reconstruction of Nyquist data converters follow.

Delta-Sigma Modulators,This chapter provides a general overview on the discrete-time .Ms (DT.Ms) and continuous-time .Ms (CT.Ms). An introduction on two different topologies of implementing high-order CT.Ms, single-loop and MASH, is presented. The benefits of employing a MASH topology for CT-.Ms are also discussed in this chapter.

Joseph Krau?,Martin Berger,Walter Helmers and next generation wide-bandwidth telecommunication standards. Compared with high-order single-loop implementations, MASH CT.Ms show superior stability and overload recovery capability. Therefore, MASH modulators tolerate more out-of-band noise and show a promising potential for wide-bandwidth and

The anti-aliasing characteristics of feedback and feedforward loop filter topologies are compared. The effects of non-idealities such as the excess loop delay (ELD) and

A CT.M employs a 7-bit quantizer, from which the four most significant bits are used in a fourth-order .M loop. The remaining three least significan

Each stage consists of an active-RC integrator, a current-steering DAC, and an EELU quantizer. An FIR filter in the main 1.5-bit DAC improves the modulator’s jitter sensit
