Abstract
An oscillator circuit and an oscillation stabilizing method are provided that can improve the productivity of products, stabilize an oscillating operation, and achieve more stable operations for a system supplied with oscillation output. An output from a variable capability oscillator circuit is received by two inverters having different threshold values. Regarding voltage values that are exceeded when oscillation is stabilized in the inverters, the boundaries of the voltage values are set as an astable boundary and an astable boundary which are the threshold values of the inverters, outputs from the inverters are counted by a stable oscillation period shortening circuit based on the timing of a clock used for the system, and the capability of the variable capability oscillator circuit is maximized until oscillation is stabilized, thereby further shortening a stable oscillation period.
