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...
This paper describes the design of a fully differential RF front-end for a low data rate FM-UWB based P-PAN receiver. The RF front-end includes an ultra-wideband LNA and a wideband RF demodulator. The receiver is designed using a standard six metal layer 0.8 mum CMOS process. The differentially configured LNA provides a 30 dB bandpass gain and offers a 2 GHz -10 dB bandwidth. Based on a passive delay...
