Abstract
Deep submicron CMOS technology proves to be suitable for transceiver design at mmwave band frequencies. At the same time, it has been a challenging task to obtain high performance at mmwave frequencies. In this paper, a 28[Formula: see text]GHz low-IF receiver frontend with improved performance by incorporating a proposed linear Gm-C low-pass filter (LPF) is presented using 40[Formula: see text]nm CMOS technology targeting for 5G wireless system. A mathematical expression for the linearity of the proposed filter is derived and compared with the basic filter model. The improved linearity (IIP3 of [Formula: see text][Formula: see text]dBm) of the proposed filter results in the enhancement of linearity and hence the Figure of Merit (FOM) of the receiver with the proposed filter. The receiver attains a conversion gain of 34.6[Formula: see text]dB, a noise figure of 3.1[Formula: see text]dB and IIP3 of [Formula: see text][Formula: see text]dBm. The total current drawn by the receiver is 27.3[Formula: see text]mA at a 1.2[Formula: see text]V power supply. The overall FOM of the receiver with the proposed filter is improved to 0.30 whereas the FOM of the receiver with the basic filter model is 0.13. The area of the receiver is [Formula: see text] whereas the proposed filter occupies [Formula: see text].
