摘要
This paper presents a capacitive-discharging oscillator architecture that achieves ultra-low-power operation without a temperature-stabilized reference generator by directly relying on the RC time constants of capacitors discharging across passively-temperature-stabilized resistive elements. The architecture operates by pre-charging two capacitors to the supply voltage, and then discharging one of...
