Abstract: In this paper a systematic design methodology
for high-order multi-bit continuous-time Delta-Sigma modulators is proposed. It provides a straightforward method for determining the coefficients of the modulator. The method is illustrated for a 4th-order 4-bit modulator with OSR of 8, while 20 MHz signal bandwidth and 12 bit resolution is achieved. The required GBW of the first integrator is less than 1.5 times the sampling frequency, which greatly reduces the overall power consumption.
