Abstract :In this work tunable radio frequency insert ignore into journalissuearticles values(RF); receiver insert ignore into journalissuearticles values(Rx); integrated circuit insert ignore into journalissuearticles values(IC); was demonstrated. TSMC 65 nm technology node was selected to implement IC. RF technique has some advantages over biomedical optic molecule investigation methods since it is easy to design, implement. Experimental measurement on live tissue is much easier than optic methods. Nanoscopic creatures have specific binding structures. Their elements construct their shapes and neighborhood conformation between their own atoms. Based on this work differential RF waves will be used to investigate the nanoscopic creatures. Since the investigation of nanoscopic creatures will require to use electromagnetic wave phase shift and scan of different RF frequencies, ultra-wide band insert ignore into journalissuearticles values(UWB); tunable receiver circuit topology was designed and simulated. For this purpose, Rx block was designed, and simulation work was demonstrated here. In the circuit simulations, off-chip antenna was connected to the low-noise amplifier insert ignore into journalissuearticles values(LNA); circuit. Specific frequency was around 30 GHz. Frequency tuning was adjusted by changing the source and bias voltages at the active inductor voltage-controlled oscillator insert ignore into journalissuearticles values(VCO); circuit block. The same VCO block was also used at the Tx circuit before. Antenna signal was modeled by using 33 GHz alternative sinusoidal signal. Antenna signal and 30 GHz active-inductor VCO voltage output were mixed at the mixer circuit block, 3 GHz envelope signal was extracted in this work. Layout implementation of Rx receiver IC was demonstrated.
