This invention relates to integrated circuits and more par ticularly to digital-to-analog
converter integrated circuits. 2. Description of the Related Art In general, a multi-bit digital-to …

(57) A noise-shaping signed digital-to-analog converter is described. A method includes
selectively enabling a first sequence of unit elements of a plurality of unit elements of a …

The current paper aims at presenting a low-power second-order input-feedforward
continuous-time (CT) ΔΣ modulator for audio applications. It uses a 4-bit asynchronous …

A novel multi mode low pass hybrid continuous/discrete time delta sigma modulator which is
suitable for low power wide band applications is presented in this article. The proposed …

This paper presents a design and simulation of a reconfigurable delta sigma modulator
(DSM) that can handle GSM/WCDMA/WLAN standards. The modulator makes use of a low …

A first order of DWA (data weighted averaging) technique is proposed to improve 6-bit digital-
to-analog convertor (DAC). In addition, this paper discusses the impact of mismatch between …

In general, the noise shaping responses, a cyclic second order response is delivered by the
method of data weighted averaging (DWA) in which the output of the digital-to-analog …
