This paper offers study review of high resolution quantisation schemes for RF-upconverter structures. The quantisation application in this structure has the function of noise shaping filter which is to distribute quantisation errors or noise at the lowest position in the desired signal band. Technically, it can simply input the input signal twice the bandwidth and reduce the noise quantisation in the desired signal band. The method used is variety where quantisation version using all variable clock periods and constant phase references. This method will also be useful in the selection of variations in over sampling ratio (OSR) and offset frequency (foffset) used for various quantisation levels used when the baseband tuning procession will be applied. All digital signal processing (DSP) systems scale with the sample rate and so the higher the sample rate the larger the bandwidth of the noise transfer function null. This is clearly desirable that such ΔΣ systems are one of potential solutions. This also includes their quantiser technique. It is therefore important to make any quantisation process fast in best high resolution.
