Abstract
Correct estimation of symbol timing, Carrier Frequency

Offset (CFO), and Signal-to-Noise Ratio (SNR) is crucial

in Orthogonal Frequency Division Multiplexing (OFDM) communication.

Typically, high estimation accuracy is desired, but often

comes with increased complexity. Which has a direct repercussion

in energy consumption. In this article, an architecture based on

Sign-Bit estimation with low complexity, and hence low power

dissipation, is presented. The architecture, is capable of estimating

the afore-mentioned parameters in virtually any OFDM

standard. The proof of concept has been fabricated in 65 nm

CMOS technology with low-power high-VT cells.... (More)

CMOS technology with low-power high-VT cells. Measurements

performed with supply voltage of 1.2V. resulted in a power

dissipation of 350 μW, 6 times smaller to that of an equivalent

8-bit architecture, and the lowest power density reported in

literature. (Less)
