Abstract—In this paper, a new technique for realizing area-ef-
ficient, low-noise filters is introduced. The proposed filter topolo-
gies utilize noise shaping techniques to shift the noise of the pas-
sive and active filter components out of the passband of the filter.
This is illustrated by implementing a programmable noise-shaped
post-mixer gain-filtering circuit for a CMOS Mobile-TV tuner. The
proposed circuits relax the noise–linearity tradeoff in the receiver
chain by providing blo
