Front-end integrated circuit design for bluetooth receiver
Zhiliang Hong · Systems engineering and electronics · 2004
A front-end circuit for bluetooth low intermediate frequency receiver including LNA, Mixer, ACF is described. Some improvements are performed for the mixer, which reduce its noise contribution and enable direct current coupling between mixer and ACF and thus avoid voltage gain stage between them. Based on 0.35 μm technology, simulation results show that the performance of the circuit meets the requirements for bluetooth receiver.
