A 32-mW 320-MHz Continuous-Time Complex Delta-Sigma ADC for Multi-Mode Wireless-LAN Receivers

Asynchronous Analogue-to-Digital Conversion Techniques

“…Another popular architecture is the Sigma-Delta ADC (Arias et al, 2006) that is based on oversampling of the analogue input. The sampling frequency is much higher than the Nyquist limit and modulates the analogue input within the sampling period.…”

ADCs and DACs for Software‐Defined Radio

“…The derivation of building block specifications from a specified standard is a very complex task that involves a multitude of trade-off decisions, which is outside the scope of this chapter. Table 6.1 summarizes some numbers available in the literature [1][2][3][4][5], to serve as a frame of reference. Table 6.1 allows us to derive some general specifications of a flexible multistandard transceiver for current wireless standards.…”

Systematic top-down design of reconfigurable ΣΔ modulators for multi-standard transceivers

“…Several multi-standard RDM ICs have been reported [10][11][12][13][14][15][16][17][18][19][20][21]. Many of them are designed to operate under several cellular communication standards [10][11][12][13][14][15][16] (from GSM to UMTS), whereas only a few are used in wireless data networks [16] or in a combination of cellular and data communication standards (UMTS and WLAN in [17]).…”

“…Many of them are designed to operate under several cellular communication standards [10][11][12][13][14][15][16] (from GSM to UMTS), whereas only a few are used in wireless data networks [16] or in a combination of cellular and data communication standards (UMTS and WLAN in [17]). Except for [4,17,18], all reported designs cover the different standard requirements by only varying the applied oversampling.…”
