The designer of a continuous-time delta sigma modulator is faced with a myriad choices - how should I choose the oversampling ratio, order of the noise transfer function, and number of quantizer levels in my design? What architecture should I employ for the loop filter? What DAC should I use? What kind of opamp(s) are apt? After all, every published work seems to demonstrate the efficacy of the authors’ design choices.
This talk, in a tutorial fashion, dissects various choices and design and hopes to infuse clarity into the design process. Practical design examples, and case studies that present an apple-to-apple comparison of some popular techniques will be discussed.
