One of the most important parameters of implanted chip in body is its ability to work for a long time without the need for battery change. Hence designing radio frequency transceivers used in these chips should be done with the lowest possible power consumption. Of course it should be noticed that for correct communication, standard specifications must be meeted. In this thesis, a receiver in medical implant communication service standard with the goal of minimal power consumption is designed. In circuit design different challenges such as low inductor quality factor, threshold voltage of transistors and usual trade-offs between receiver parameters are faced. Therefore, previous used... 

In the communication systems, there are two types of blockers: in-band and out-of-band. High frequency pre-filters and band-pass filters can be used to suppress the out-of band blockers. However, using these methods does not affect the in-band interferers. Spatial filtering by means of phased array antennas and using frequency filtering can suppress both types of interferers. In a typical phased array receiver, all of the received signals pass through active blocks (such as LNAs, active phase shifters, driver amplifiers, etc.) that amplify the interferers before canceling them. Therefore, because of the high strength of the interferers, the dynamic range of the front-end blocks preceding...
