OSCILLATOR CIRCUIT, SEMICONDUCTOR DEVICE PROVIDED WITH SUCH OSCILLATOR CIRCUIT, AND SEMICONDUCTOR MEMORY DEVICE PROVIDED WITH SUCH OSCILLATOR CIRCUIT

摘要: PROBLEM TO BE SOLVED: To provide an oscillator circuit in which a stable frequency can be obtained by stopping oscillating operation or preventing the output of oscillated signal while oscillation is unstable when starting capable controlling start/stop. SOLUTION: An part 5 turned into enable state permitting (EN) and control 4 starts operating. The operating changes (VR) to value corresponding prescribed set. Besides, outputs accordance with detection (MON) inputted 1, compared outputted after reach detected. Thus, transient detected caused not outputted. COPYRIGHT: (C)2003,JPO
