A 0.6-V, 69-dB subthreshold sigma–delta modulator

C Chen, H Zhang - Journal of Semiconductors, 2018 - iopscience.iop.org
In this paper a 0.6 V, 14 bit/500 Hz subthreshold inverter-based sigma–delta modulator is
proposed. In the first integrator of the modulator, a bootstrap switch is used to accomplish …
