This engineering paper describes a third-order continuous-time current-mode ΣΔ modulator designed for WLAN 802.11b applications. It proposes a modified current mirror integrator and a dynamic latch-based current comparator aimed at improving bandwidth, linearity, and sampling rate. The authors report >60 dB dynamic…
