Ultra low-power, -area and -frequency CMOS thyristor based oscillator for autonomous microsystems

2015 Nordic Circuits and Systems Conference (NORCAS): NORCHIP & International Symposium on System-on-Chip (SoC), 2015
In this paper we present a minimal sized CMOS thyristor based oscillator, which is able to provide a clock signal of $$\approx$$ź20 Hz. The oscillator was designed as a timer or clock generator for autonomous microsystem applications. The chip area of the oscillator is 18 µm by 35 µm and it is able to run for more than 10 min when supplied from a 10 nF

An ultra-low frequency ring oscillator with programmable tracking using a phase-locked loop

2012 IEEE 55th International Midwest Symposium on Circuits and Systems (MWSCAS), 2012
This paper presents a programmable ultra-low frequency ring oscillator designed in a 0.5µm CMOS technology with 3.3 V power supply. In normal operation, the oscillator produces a periodic signal without external inputs (other than power and ground).

Ultra-low power frequency synthesizer based on a dual-locking ring oscillator

2016 13th IEEE International Conference on Solid-State and Integrated Circuit Technology (ICSICT), 2016
An ultra-low power frequency synthesizer based on a 28-nm CMOS dual-voltage controlled ring oscillator is presented. The technological dispersion and temperature effects are tackled thanks to a Delay locked loop (DLL) which sets a coarse tuning voltage.

Suppression Strategy of Ultra-Low Frequency Oscillation in Yunnan Power Grid with BESS

2019 North American Power Symposium (NAPS), 2019
Many problems related to power system frequency have occurred in Yunnan Province ─a province in southwestern China with high proportion of hydro-turbine generators. Yunnan Power Grid is a typical direct-current (DC) sending grid and the installed capacity of hydro-generators has accounted for more than 70% of the total capacity after asynchronous ...
