This paper presents a design of a novel cascaded third-order feed-forward delta-sigma analog-to-digital converter (ADC). This ADC is realized using fully differential switched capacitor architecture and produces a 12-bit resolution at a data output rate (DOR) of 2.5 MS/s for RF wireless applications. The delta-sigma modulator consists of a second-order single-bit feed-forward modulator cascaded with a multi-bit first-order modulator. The cascaded feed-forward third-order (2-1) ADC is simulated using Matlab and Simulink. The delta-sigma modulator was designed using Cadence Virtuoso in TSMC 0.18 μm CMOS technology. The power consumption of the designed modulator is 12.74 mW, and the resolution is 11.85 bits for an over-sampling ratio (M = 32). The figure of merit is 1.38 pJ at a sample rate of 80 MS/s. The proposed delta-sigma modulator is compared with other state-of-the-art low-pass delta-sigma modulators in terms of their speed, power, DOR, and the proposed modulator has one of the lowest power consumption.

Zespół metod wykorzystywanych do planowania eksperymentów określa się jako Design of Experiments -DOE. Celem stosowania DOE jest uzyskanie jak największej ilości wartościowych i wiarygodnych informacji o badanym wyrobie lub procesie na podstawie jak najmniejszej liczby doświadczeń. W artykule zwrócono uwagę na stosunkowo mało znane metody opracowane przez Shainina oraz Taguchiego. Przedstawiono dobór parametrów metodą Shainina i Taguchiego na przykładzie procesu toczenia.
