This paper presents an integrated 2-PPM CMOS demodulator for non-coherent energy detection receivers which inherently provides analog-to-digital conversion. The device, called Bi-phase integrator, employs an open loop Gm - C integrator loaded with a switched capacitor network. The circuit has been simulated in a mixed-mode UMC 0.18mum technology and its performance figures are obtained through a mixed-signal simulation environment developed with the aid of ADVanceMS (ADMS, mentor graphics). Bit-error-rate simulations show that the circuit performance is about the same of an ideal energy detection receiver employing infinite quantization resolution. In addition, the simulations show that the circuit provides a complete offset rejection. Thanks to its low power consumption (1 mW during demodulation), its application is appealing for portable devices which aim at very low-power consumptions.

Abstract

This paper presents an integrated 2-PPM CMOS demodulator for non-coherent energy detection receivers which inherently provides analog-to-digital conversion. The device, called Bi-phase integrator, employs an open loop Gm - C integrator loaded with a switched capacitor network. The circuit has been simulated in a mixed-mode UMC 0.18mum technology and its performance figures are obtained through a mixed-signal simulation environment developed with the aid of ADVanceMS (ADMS, mentor graphics). Bit-error-rate simulations show that the circuit performance is about the same of an ideal energy detection receiver employing infinite quantization resolution. In addition, the simulations show that the circuit provides a complete offset rejection. Thanks to its low power consumption (1 mW during demodulation), its application is appealing for portable devices which aim at very low-power consumptions.
