This paper proposes an energy-efficient, 12-stage charge pump with constant threshold voltage. This new charge pump utilizes 2 pairs of non-overlapping clocks. Under control of an extra pair of clocks, each charge pump cell (CPC) is equivalent to a switch. Without reduction by a threshold voltage and the limitation of body effects, a higher output voltage(More)
This paper proposes new structures of multi-stage noise-shaping (MASH) sigma-delta ADC by applying second-order noise-coupling technology to conventional MASH modulators. The proposed architectures take advantage of the extra noise-coupled path to achieve a second-order noiseshaping increase as well as save the number of active devices. Theoretical analysis(More)
