An, X. (author), Pan, S. (author), Jiang, H. (author), Makinwa, K.A.A. (author)CMOS frequency references based on RC oscillators are usually preferred over bulky crystals in loT applications [1-5]. However, due to the process spread and finite temperature coefficient (TC) of most on-chip resistors, RC oscillators require trimming and temperature compensation to achieve decent accuracy. Enabled by high-resolution...conference paper 2023

Jiang, Chuanning (author), An, Xizhong (author), Li, Meng (author), Wu, Yuhang (author), Gou, Dazhao (author), Wu, Yongli (author)Mixing structures and characteristics are crucial to the mixing quality of spherical/cylindrical binary granular systems like the biomass-coal mixtures which can affect energy release and carbon emissions. In this work, the mixing of binary spheres/cylinders in a rotating drum was numerically reproduced by using discrete element method (DEM)....journal article 2023

Pan, S. (author), An, Xiaomeng (author), Yu, Zheru (author), Jiang, H. (author), Makinwa, K.A.A. (author)This article presents the design and implementation of a compact CMOS RC frequency reference. It consists of a frequency-locked loop (FLL) that locks the period of a voltage-controlled oscillator (VCO) to the time an RC network takes to charge to a reference voltage. Conventionally, an RC time constant with a near-zero temperature coefficient...journal article 2023
