Low-Power Bluetooth Receiver Front End Design with Oscillator Leakage Reduction Technique

摘要

This paper presents a Bluetooth Low Energy (BLE) based receiver that features a low power LNA and a novel passive AND function mixer. The entire receiver is designed and simulated in the TSMC 65 nm planar CMOS technology. The receiver benefits from a direct down conversion techniquewhere the baseband signals are separated into I/Q paths based on the phase of the signal. The overall input sensitivity of the receiver is around –65 dBm, whilst the system has an overall noise figure (NF) of 8 dB. The overall conversion gain of the system is 17.5 dB and the entire receiverconsumes 2.85 mW.
