Design of coplanar waveguide matching circuit for RF-CMOS front-end

Development of Cmos Coplanar Waveguide Matching Circuit for Rf Front-end

For realizing a single chip microwave front-end, we studied the new design theory of impedance matching circuits for a Si-CMOS low noise amplifier (LNA) or power amplifier (PA), which are composed of coplanar waveguide (CPW) meanderline resonators and impedance inverters. We also present the simulated performances of CMOS-LNA or PA connected with input and output matching circuits. Finally, we ...

RF front-end CMOS design for build-in-self-test

Active Inductor Designs for RF CMOS Receiver Front - End

Inductors are a necessary building block in many circuits, including LNA and oscillators largely used in Receivers and various other systems. Because planer inductors can occupy a large amount of area in integrated-circuit (IC) designs, the search has been on for smaller, tunable inductors suitable for monolithic fabrication In this paper a method, which is to implement an active inductor by CM...

AMS/RF-CMOS circuit design for wireless transceivers

Mobile phones have evolved from ''simple'' devices allowing phone calls over a wireless link to ''all-in-one'' devices. Besides keeping us always best connected, handheld devices have become true multimedia centers where we can watch movies or our favorite team's soccer game while making a phone call or chatting over the internet. Hence, in mobile terminals, multi-standard capability is to be s...

Current-mode design techniques in low-voltage 24-GHz RF CMOS receiver front-end

A new high frequency CMOS current-mode receiver front-end composed of a current-mode low noise amplifier (LNA) and a current-mode down-conversion mixer has been proposed in the frequency band of 24 GHz and fabricated in 0.13-lm 1P8M CMOS technology. The measurement of the current-mode receiver front-end exhibits a conversion gain of 11.3 dB, a noise figure (NF) of 14.2 dB, the input-referred 1-...
