Description
Summary:This paper presents a complete ultra-low power receiver with direct down conversion architecture. It is designed as Wake-up Receiver for wireless sensor nodes. The 130nm CMOS chip includes envelope detector, low noise baseband amplifier, PGA, mixed-signal correlation unit and auxiliaries for stand-alone operation. At 868MHz, a receiver sensitivity of -71dBm is achieved with total power consumption of 2.4μW at 1.0V supply by means of baseband correlation over 7ms with 64 bit pattern, 99% detection probability and a false wake-up rate of 10 3 /s.
