| titleOfInvention | Low-power-consumption high-resolution continuous-time Sigma-Delta modulator |
| abstract | The invention discloses a low-power-consumption high-resolution continuous-time Sigma-Delta modulator, wherein a 3-order CIFF-B structure is adopted in the system architecture design, and the power consumption and the performance are better balanced on the basis of the CIFF and CIFB architectures; the design of the operational amplifier in the integrator adopts a two-stage Class AB structure working under 1.2V power supply voltage and a low-power consumption limited low-frequency gain compensation scheme, thereby meeting the requirements of system resolution and linearity and well controlling power consumption; an FIR filter is added in front of the feedback DAC, so that the deterioration of the system performance caused by clock jitter can be better inhibited, the index requirement on an operational amplifier can be reduced by inhibiting the high-frequency change of a feedback waveform, the linearity of the system is increased, and the feedback waveform is changed from a common NRZ waveform to an RZ waveform, so that the influence of ISI is avoided. The extra power consumption brought by the scheme is very small, and the reduction of the system power consumption is facilitated. |
