Design exploration of a 65 nm Sub-VT CMOS digital decimation filter chain
Author
Summary, in English
of digital half-band filters operating in the sub-threshold
(sub-VT) region with throughput and supply voltage constraints.
A 12-bit filter is implemented along with various unfolded
structures, used to form a decimation filter chain. The designs
are synthesized in a 65 nm low-leakage CMOS technology with
various threshold voltages. A sub-VT energy model is applied to
characterize the designs in the sub-VT domain. The results show
that the low-leakage standard-threshold technology is suitable
for the required throughput range between 250Ksamples/s and
2Msamples/s, at a supply voltage of 260mV. The total energy
dissipation of the filter is 205 fJ per sample.
