We present in this paper an ultra low power ISM band RF receiver intended for implantable biomedical devices. The proposed circuit, which represents the reception part of a new energy- efficient RF FSK transceiver, consist of an FSK receiver (Rx) with OOK fully passive wake-up device (WuRx). This WuRx is batteryless with energy harvesting technique which plays an important role in making the RF transceiver energy-efficient. This proposed receiver is achieved with a reduced hardware architecture which does not use an accurate local oscillator, high Q external inductor and I/Q signal path. The circuit is base on a dual injection locked FSK-to-ASK conversion technique. The circuit is implemented in IBM 0.13 mu m CMOS technology with 1.2 V supply voltage. This WuRx achieves a data rate of 100 kbps for 0.2 mu W power dissipation at -53 dBm input signal. The Rx shows -78 dBm sensitivity for 8 Mbps data rate while consuming 639 mu w power.
