A 0.5 V 3.1 mW Fully Monolithic OOK Receiver for Wireless Local Area Sensor Network

A low voltage (0.5 V) low power (3.1 mW) on-off keying (OOK) miniaturized (380 mum times 220 mum) monolithic receiver implemented in 0.18 mum CMOS technology for wireless local area sensor network is demonstrated. This chip can receive small radio signal well with a sensitivity of - 50 dBm (-62 dBm) and a maximum data rate of 2 Mbps at 433 MHz (150 MHz). When operated at 0.45 V, this receiver consumes less power (1.36 mW) with the same maximum data rate but a degraded sensitivity (-35 dBm) at 433 MHz
