Lu, Qi (author), Li, Shuangmu (author), Zhao, Bo (author), Jiang, Junmin (author), Chen, Zhiyuan (author), Du, S. (author)Multiple voltage conversion ratio (VCR) recursive switched-capacitor (SC) dc-dc converters, based on several basic 2:1 converters, are widely used for on-chip power supplies due to their flexible VCRs for higher energy efficiency. However, conventional multiple VCR SC converters usually have one or more 2:1 converters unused for some VCRs,...journal article 2023

Brito Zamparette, R.L. (author), Makinwa, K.A.A. (author)This letter presents a low-power, fully integrated current sensor for Coulomb-counting. It employs a hybrid delta–sigma modulator ( ΔΣM ) with an FIR-DAC to digitize the voltage drop across a shunt. The modulator’s first stage consists of a capacitively coupled chopper amplifier, which enables a beyond-the-rails (−0.3 to 5 V) input common...journal article 2022

Babaie, M. (author), Kuo, F (author), Chen, H (author), Cho, L (author), Jou, C. P. (author), Hsueh, F. L. (author), Shahmohammadi, M. (author), Staszewski, R.B. (author)We propose a new transmitter architecture for ultra-low power radios in which the most energy-hungry RF circuits operate at a supply just above a threshold voltage of CMOS transistors. An all-digital PLL employs a digitally controlled oscillator with switching current sources to reduce supply voltage and power without sacrificing its startup...journal article 2016
