Sar dither
Webb23 mars 2024 · This project shows how to model a 10-bit pipeline ADC and a 10-bit DAC using ideal components. Used vdc, vpulse, vcvs, switch, res, cap, vccs to construct the 10-bit ADC based on 1-bit per stage pipelined architecture. Models are built in Cadence using ideal components & VerilogA blocks, & Analysis is done on Matlab. WebbFig. 3 shows the block diagram of the prototype 12-bit SAR ADC. The design utilizes the traditional 1-bit/step architecture, which preserves most advantages of SAR, such as the …

Webbsource of the dither is a pseudo-random noise generator. The dither must be attenuated so that at the ADC input, it has an rms level of (/3 LSB, which is given by: vdither e 1 3 VREF 2n For a 10-bit converter with VREF e 5V, we have vdither e 1.6 mV. The signal and dither are filtered through an 8th order Chebyshev low pass filter with a 20 kHz ...
