Abstract
The evolution of 5g technology for the upcoming generation of high-speed applications demands a substantial drive for innovation to develop a more extensive wireless communication system. This dissertation aims to address the challenges associated with high speeds and overcome trade-offs to enhance coverage performance for the 5g new radio c band receiver. It introduces a high figure of merit (fom) 5g new radio wideband receiver system, designed for sub-6 ghz c band applications and implemented using the 130 nm cmos silterra process. The receiver system incorporates a dual-stage low noise amplifier (lna) configuration to achieve a high and consistent gain across the target bandwidth of 3 to 5 ghz, without sacrificing linearity, noise figure, and stability. The lnas are integrated with an innovative iq generator circuit to ensure rf quadrature generation at four phases: 0°, 180°, 90°, and 270°. The double balance mixer, integrated with the iq generator circuit, is supported by 3 to 5 ghz free-running tailless hybrid vcos to form i and q intermediate frequency (if) of 100-200mhz, further enhanced with stacked transimpedance amplifier (tia) stages. Consequently, the entire proposed receiver system achieves key parameters of 35.6 db gain, linearity of 16.1 dbm, and a noise figure (nf) of 4.2 db under 12mw power consumption.
