Abstract

There is increasing interest in the use of CMOS circuits for high frequency highly integrated wireless telecommunications systems. This paper presents the results of on-going work into the development of a cell library that includes many of the circuit elements required for the high frequency sub-systems of communications integrated circuits. The cell library studied included an RF control element, single ended Class A amplifier, RF isolator, and Gilbert cell mixer circuit topologies. Circuit design criteria and measurement results are presented. All cells were fabricated using standard 2.0, 1.2, and 0.8 μm CMOS integrated circuit fabrication processes with no post-processing performed. The results indicate that 2.0 μm CMOS can be used successfully up to approximately 250 MHz with 0.8 μm cells useful up to approximately 1000 MHz.
