Impulse radio ultra wideband on-off keying detector

Abstract

The invention provides an impulse radio ultra wideband on-off keying detector. The impulse radio ultra wideband on-off keying detector comprises a square unit circuit and an integral detection unit circuit, wherein the output end of the square unit circuit is connected with the input end of the integral detection unit circuit. The impulse radio ultra wideband on-off keying detector carries out shaping and amplification on signals by utilization of the square unit circuit, and full wave voltage signals are converted into half-wave current signals. An NMOS pipe M9 works in a sub-threshold area, when an input current signal of the integral detection unit circuit is increased, the output current of the NMOS pipe M9 is reduced, when an input current signal of the integral detection unit circuit is reduced, the output current of the NMOS pipe M9 is increased, and then stray capacitance of an MOS pipe M12 and an MOS pipe M14 and on resistance of the MOS pipe M12 and the MOS pipe M14 are used for conducting integral detection. The impulse radio ultra wideband on-off keying detector can be applied to an existing IR-UWB receiver technology for improving detection efficiency, therefore, the purpose of simplifying the structure of LNA and the structure of VGA is achieved, whole machine power consumption of a receiver can be finally reduced, and using demands in low speed low power consumption wireless communication are met.
