This paper presents the design and measurement results of low gain RF front-end manufactured in 90nm CMOS covering the frequency range of 0.5-6GHz. The front-end is a modified form of a balanced active mixer to enhance its gain and achieve wideband input matching. The transconductance stage of a mixer is split into NMOS-PMOS inverter pair for better linearity and partial noise cancellation. The inverter...
A 1.2-V broadband down-conversion mixer for ultra-wideband (UWB) system applications is presented. The mixer is fabricated in the 0.18-mum 1P6M standard CMOS process. To achieve a low DC power consumption for UWB applications, the LC folded-switching approach is utilized to reduce the supply voltage and the DC power consumption. A CMOS inverter with current-reuse technique is used in the transconductance...
