چکیده
To increase the productivity in various sectors, foundation can be made based on mobile communication solutions to different problems. SDR is the preferred technology to stitch together advanced services for ubiquitous global mobile connectivity. We have investigated in the present study the Sigma Delta ADC, one important component of SDR. Improvement in Dynamic Range including the SFDR with a oversampling process have been shown in the presence of real life imperfection. It also gives better SNR for SDR mobile receiver. Various features of a wide band high linearity Sigma Delta ADC have also been described.

متن کاملConcurrent Adaptive Cancellation of Quantization Noise and Harmonic Distortion in Sigma–Delta Converter
Adaptive noise cancellation (ANC) technique can removes thermal and shaped wideband quantization noise from the output of sigma-delta modulator and improves SNR and SFDR ratios. ANC filter more than desired signal passes harmonics of input signal caused by analog element such as operational amplifier of the integrator without any suppression and this issue causes less increment in SNR and SFDR ...

The ability of high performance Radar and Broadband Systems to detect weak targets in presence of strong interferers or clutter is given by their Spurious Free Dynamic Range (SFDR). Although the Signal-toNoise-Ratio (SNR) necessary for detection may be improved by well-known system processing gains, the dynamic range is ultimately limited by distortion terms caused by nonlinear behaviour of rec...
