Design of a CMOS Tx RF/IF Single Chip for PCS Applications

PCS 응용을 위한 CMOS Tx RF/IF 단일 칩 설계

In this paper, a CMOS Tx RF/IF single chip for PCS applications is designed. The chip consumes 84mA from a 3V supply and the layout area without pads is 1.6mm$\times$3.5mm. Simulation results show that the RF block composed of a SSB RF block and a driver amplifier exhibits a gain of 14.8dB and an OIP3 of 7dBm. The image and carrier suppressions are 35dBc and 31dBc, respectively. The designed circuits are under fabrication using a 0.35${\mu}{\textrm}{m}$ CMOS process.
