Abstract
This paper presents an analysis on energy dissipation

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... (More)
