Design of Low Power, Low Voltage Sub-Sampling Receiver for Wireless Body Area Network
The release of the IEEE802.15.6 standard has led to increased interest in low-power technologies for wireless body-area-networks (WBAN). The power dissipation, supply voltage, and IC area are some of the most important criteria for successful WBAN implementations. Digital-intensive RX architectures can potentially result in sub-1V operation with significant reductions in power consumption and area, but require system and circuit-level innovations to achieve desired sensitivity and linearity. A mostly-digital 2.4GHz RX architecture that uses a sub-sampling technique with digital IF/baseband signal processing is implemented to enable low power (1.3mW) and low voltage (0.6V) operation, resulting in ~3x reduction in power consumption with comparable performance to prior art.
