A 60 GHz, 50 mW, 3dB Noise Figure Receiver Frontend Using UMC 40 nm CMOS technology

Abstract

In this work the low-IF receiver for 60 GHz wireless system is presented using 40nm CMOS technology. The individual blocks of receiver front-end includes 3-stage low noise amplifier (LNA), mixer, low pass filter (LPF). These blocks are optimized for low power while maintaining other performance metrics. The Radio Frequency (RF) receiver front-end with 3stage single-ended LNA and differential LNA were designed and compared. The incorporation of current amplifier improves the overall performance of receiver. It was observed that RF frontend receiver with single-ended LNA offers 31.11 dB conversion gain (CG) and 3.35 dB noise Figure (NF) whereas receiver with differential LNA offers 41.13 dB CG and 2.63 dB NF. From the results it can be seen that the performance of differential LNA receiver is better than single ended LNA receiver. The details of the design suggest that receiver with differential LNA can be a potential candidate for the transceiver applications.
