Abstract

In this paper a fully differential implementation of a delay-line RF demodulator for FM-UWB based P-PAN receivers is presented and discussed. The implementation makes use of a dedicated circuit to remove possible phase imbalance in the differential signal pair. Without this correction demodulation performance is seriously affected. Detailed transistor-level simulation results are presented based on a standard 0.18 μm CMOS process. The simulations show that the presented demodulator can provide a 2GHz bandwidth (3-5 GHz) and an overall demodulation gain of 52dBV^-1. The circuit consumes 3.2 mA using a 1.8 V power supply
