This paper discusses the use of sigma–delta modulation as the primary processing block in power D–A systems. The focus is on the pulse repetition frequency (PRF) of the one-bit output and its suitability for power switching. It is shown that in order to preserve high power efficiency and...
This article proposed a discrete-time single-loop 3rd order 5-bit Sigma-Delta (ΣΔ) modulator for the audio applications. In this modulator, a feed forward path is used to relax the design requirement...
Systematic design of a low power, wideband and multi-bit continuous-time delta-sigma modulator (CTDSM) is presented. The design methodology is illustrated with a 640 MS/s, 20 MHz signal bandwidth 4th order 2-bit CTDMS implemented in 0.18 µm CMOS technology. The implemented design...
