Abstract
An integrated ultra-wideband CMOS RF front-end for UWB 6-9 GHz application is presented in this paper. A single-in-differential-out gain controllable low noise amplifier and a current-reuse bleeding IQ merged quadrature mixer are integrated as the RF front-end. This ESD protected module is implemented in TSMC 0.13μm RF CMOS process and the post-layout simulation results shows that it achieves a high voltage gain of 23.7-25.1dB and a low voltage gain of 10-12.4dB, an averaged total noise figure of 4.6-5.1dB while operating in the high gain mode and an in-band IIP3 of -6.7dBm while the low gain mode. This RF front-end consumes 22.4mA from a 1.2V supply voltage.
