This paper presents a wideband direct ΔΣ receiver for the 0.7–2.7 GHz frequency range. The architecture embeds a wideband direct-conversion RF front-end into a continuous-time feedback ΔΣ modulator, which initiates the analog-to-digital conversion of the selected channel already at the RF nodes. A feedback-type architecture enables simultaneous filtering of nearby interfering signals. The inductorless 40 nm CMOS receiver supports programmable ΔΣ modulator coefficients and RF channel bandwidths… CONTINUE READING
