In this work, a 3–5 GHz CMOS UWB RF receiver front-end design is described. The design was realized using integrated passive device (IPD) package format as system-in-package (SiP) application. The CMOS circuit consists of a fully differential common gate-low noise amplifier (CG-LNA), an IQ downconversion mixer, and a variable gain amplifier. Three low loss IPD transformer baluns are used to convert...
In this paper, a 2.5-2.7 GHz direct conversion receiver front-end including a low-noise amplifier (LNA) based on a resistive shunt-feedback inverter configuration, an on-chip transformer balun of unequal turn ratio for impedance matching, and a current-driven passive mixer is presented. The LNA uses a two-stage amplifier topology established from inverters and resistors to improve the third-order...
