Abstract
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 f ront-end into a continuous-time
feedback ΔΣ modulator, which initiates the analog-to-digital con-
version of the selected channel already at the RF nodes. A feed-
back-type architecture enables simultaneous filtering of nearby in-
terfering signals. The inductorless 40 nm CMOS receiver supports
programmable ΔΣ modulator coefficients and RF channel band-
