This contribution deals with the novel conception of design approach to RF wideband and multiband receivers. New methodology of spatial sampling and spatial sampling method of standing wave is presented. Front-end RFIC receiver, utilizing spatial sampling method of standing wave for down converting to baseband and demodulation, has been proposed and analyzed. The whole system is proposed to be implemented in CMOS AMS 0.35mm technology with 2.7 V supply voltage. It works in two bands (in 2 Ghz and 5 GHz ranges). Furthermore, basic building blocks of the RF receiver, such as voltage controlled oscillator, low noise amplifier, spatial sapling unit, additive devices and power detectors have been designed and optimized.
