摘　　要：A non-coherent receiver for impulse radio ultra-wide band（IR-UWB）is presented.The proposed receiver front-end consists of a high gain LNA,a high frequency detector and an intermediate frequency（IF）amplifier to amplify the recovered signal and drive an external test instrument.To meet the requirements of high gain and a low noise figure（NF）under moderate power consumption for the LNA,capacitor cross coupled（CCC）and current reuse techniques were adopted.The detector consists of a squarer and an integrator.The overall circuit consumes 41.2mA current with a supply voltage of 1.8 V at a 400 MHz pulse rate.The resulting energy efficiency is 0.19 nJ/pulse.A chip prototype is implemented in 0.18-μm CMOS.The die area is 2.1×1.4 mm^2 and the active area is 1.7×0.98 mm^2.A non-coherent receiver for impulse radio ultra-wide band（IR-UWB）is presented.The proposed receiver front-end consists of a high gain LNA,a high frequency detector and an intermediate frequency（IF）amplifier to amplify the recovered signal and drive an external test instrument.To meet the requirements of high gain and a low noise figure（NF）under moderate power consumption for the LNA,capacitor cross coupled（CCC）and current reuse techniques were adopted.The detector consists of a squarer and an integrator.The overall circuit consumes 41.2mA current with a supply voltage of 1.8 V at a 400 MHz pulse rate.The resulting energy efficiency is 0.19 nJ/pulse.A chip prototype is implemented in 0.18-μm CMOS.The die area is 2.1×1.4 mm^2 and the active area is 1.7×0.98 mm^2.
