Abstract

Rapid advancement in RF technology coupled with the opportunity to reduce healthcare cost while improving quality of patience’s lifes by employing preventive healthcare, has led to the opening of a frequency band at 402-405 MHz [1]. This is commonly referred to as Medical Implant Communication Service (MICS) band. This band,  approved by the FCC for use with medical devices, will be utilized by RF-front-ends to communicate short range (≈2 m) with medical implants through the human body [2]. The need for embedding spurs the need for ultra-low power and small dimension transceivers for wireless communication. This project present revolves around design of an active inductor based current reuse receiver [3] front-end, implemented in the IBM 0.13 μm CMOS technology. The front-end consists of a low-noise amplifier (LNA), mixer, and a Gm-C based low pass filter. Direct modulation receiver topology is employed for the proposed receiver, as the architecture is well suited for ultra-low power applications.
