A symbol-duty-cycled 440 pJ/b impulse radio receiver with 0.57 aJ sensitivity in 130 nm CMOS

A non-coherent 130nm CMOS UWB impulse radio receiver for ultra-low energy consumption applications is presented. The receiver supports a 4.4 Mb/s data rate employing 2-PPM modulation, with a sensitivity of 0.57 aJ. Implementing symbol-level duty-cycling, such an outstanding performance is attained at an energy consumption of only 440 pJ/b.
