Abstract: Apparatuses and methods are disclosed for oscillators that are substantially insensitive to supply voltage variations. In one such example apparatus, a capacitance circuit is configured to be charged and discharged. Charging and discharging circuits are coupled to the capacitance circuit and configured to charge and discharge, respectively, the capacitance circuit by charging and discharging currents responsive to charge and discharge signals. A control circuit is coupled to the charging circuit and the discharging circuit, and is configured to provide the charge and discharge signals responsive to a voltage of the capacitance circuit, and is further configured to provide an oscillation signal responsive to the voltage of the capacitance circuit. The charging current, the discharging current, or both the charging and discharging currents are proportional to a difference between a first reference voltage and a second reference voltage.
