RF Potential of a 0.18- m CMOS Logic Device Technology
نویسندگان
چکیده
The radio-frequency (rf) performance of a 0.18m CMOS logic technology is assessed by evaluating the cutoff and maximum oscillation frequencies ( and max) the minimum noise figure ( min) and associated power gain ( ) and the 1/ -noise of the devices. Gate-biasing and channel-length and gate-finger-length adjustments are identified as means to optimize the rf performance without any technology process modifications. Changing to N2O gate dielectrics is shown to greatly reduce the 1/ noise without sacrificing the ac performance. The power amplifier characteristics of CMOS at low power levels are also discussed.

A 0.18- m CMOS CMFB DOWNCONVERSION MICROMIXER WITH DEEP N-WELL TECHNOLOGY FOR LO-RF AND LO-IF ISOLATION IMPROVEMENTS
CMOS deep N-well technology can eliminate the physical effects of NMOS transistors and reduce substrate noise and coupling in order to reach the NMOS channel. These properties result in better LO-IF and LO-RF isolations in a Gilbert micromixer. Two identical 0.18m CMOS downconversion micromixers (except at the RF input stage) with deep N-well or without deep N-well are fabricated in adjacent ar...

The design of a low noise figure (NF), high conversion gain (CG) double-balanced, Gilbert-cell mixer is presented. Since the noise figure of the RF CMOS mixer is strongly affected by flicker noise (1/f), a dynamic current injection technique is used to reduce the flicker noise corner frequency. The current injection circuitry comprises 3 pMOS to inject current pulses at the switching instants. ...
