Abstract
This paper describes a receiver system design for im-
pulse-radio ultra-wideband (IR - U W B )t h a to p e r a t e sa tt w oc a r -
rier frequencies—3.494 and 3.993 GHz—with a 10-Mbps data rate.
To reduce the power consumption of the front-end ampli fiers, a
super-regenerative architecture is used. An integrated circuit, im-
plemented in a CMOS 0.18- m technology and operating with a
1.5-V power supply, exhibits ene rgy consumption of 0.24 nJ/bit
with a measured sensitivity of 66 and 61 dBm at 3.
