چکیده
a cheaper design. Since an LC-oscillator topology is mandatory to achieve a minimal current draw, the reduction of the number of coils has to be done in the LNA, the mixer and the quadrature generator. In this work, starting from the LNA-Mixer and VCO (LMV) cell topology [2], a single-coil low-power receiver shares the bias current among all the RF blocks of the analog front-end. The receiver prototype chip consumes 3.6mW and has an active die area of 0.35mm2. It is based on a low-IF architecture and includes

Enabling Coexistence of ZigBee and WiFi
Spectrum scarcity is known to be main obstacle to scaling of wireless network capacity. Spectrum sharing is a solution to this problem. The unlicensed ISM band is getting crowded by WLAN and WPAN users and devices. Spectrum sharing within the devices of same network is not a problem. But coexistence of WLAN and WPAN (eg: WiFi and ZigBee) is a challenging problem. Spectrum sharing among these ne...
