This paper presents the design and analysis of RF Front End for Wireless Heartbeat measurement System. In this work LNA , an inductor connected at the gate of the cascode transistor and capacitive cross-coupling are strategically combined to reduce the noise and the nonlinearity influences of the cascode transistors in a differential LNA. The Mixer is implemented by using the Gilbert-type configuration, cross pmos injection technique and the resonating technique for the tail capacitance. The resulting LNA achieves 1.26 ㏈ NF, better than 1.88㏈ NF Typical. Also Mixer resulting achieves 9.8㏈ at 100㎑.
