A 3.5mW Non-coherent UWB Impulse Radio Receiver in 180nm CMOS

Abstract

One of the emerging trends in electronics is wireless technology. Ultra-Wide Band (UWB) signaling is widely used for the wireless technology compared to traditional narrow band because of the short pulses used in communication. In this paper, an impulse radio based noncoherent UWB receiver has been designed. The receiver is designed for lower band of UWB which is from 3-5GHz suitable for low power and low cost applications. In order to achieve low power, the low noise amplifier (LNA) is designed using current reuse technique and also a low power squarer, integrator and comparator is designed. The simulated result ensures that, the proposed receiver is recovering the digital information from the RF signal. The calculated receiver sensitivity is around -94dBm with the consideration of 3dB noise figure (NF) of LNA and 10MHz of baseband (BB) signal bandwidth. The receiver is implemented in 180nm CMOS and it is consuming 3.5mW from 1V supply.
