Abstract

This paper presents the design of a linear-mode super-regenerative receiver. It is targeted for low-power medical applications in the range of 402-405 MHz. The receiver provides an excellent trade-off between high performance, simplicity of architecture, and low power consumption. It is designed to be fully integrated on chip. The receiver employs on-off keying (OOK) for a 2 Mbps data rate of received data. The total power consumption is adjusted to be around 1mW at the minimum input power level -96 dBm. A clock-and data-recovery (CDR) system and an automatic gain control (AGC) feedback loop are inserted to improve its performance. The sensitivity is calculated to be -92 dBm.
