An Analog CMOS Pulse Energy Detector for IR-UWB Non-Coherent HDR Receiver

This paper presents an analog circuit aimed at performing pulse detection in the 3.1-10.6 GHz UWB band for MB-OOK high data rates receiver. Low cost and low power consumption are targeted. For that we especially focus on CMOS technology. The proposed pulse energy detector includes three stages: squarer, amplification and integration. Theoretical studies and SPICE simulation results in 0.35 μm CMOS technology are presented to validate this very low complexity approach. In particular, imperfection and mismatch effects between the squarer and amplification stages are considered.
