Abstract
A 2.4 GHz downconverter is designed using the TSMC 0.18 μm CMOS standard process for wireless sensor networks (WSN). An important goal of the design is to achieve the low supply voltage and low power consumption that is required in WSN receivers. The bulk injection technique is used to reduce the supply voltage and power consumption of the downconverter. A voltage of 0.6 V is supplied to the downconverter and the power consumption is then 0.33 mW. The simulated results of the 2.4 GHz downconverter include that a conversion gain is 8.6 dB, an input-referred 1 dB compression point (IP1dB) is −18.4 dBm, an input-referred third-order intercept point (IIP3) is −8.8 dBm, a noise figure (NF) is 16.2 dB, and a port-to-port isolation exceeds 30 dB.
