Title:
基準周波数生成回路、半導体集積回路、電子機器
Document Type and Number:
Japanese Patent JP5280449
Kind Code:
B2
Abstract:
An oscillator circuit increases and reduces signal levels of first and second oscillation signals in a complementary manner in response to a transition of a signal level of a reference clock. An oscillation control circuit compares each of the signal levels of the first and second oscillation signals to a comparison voltage, and causes the signal level of the reference clock to transition according to results of the comparison. A reference control circuit increases or reduces the comparison voltage so that a difference between a signal level of an intermediate signal which is proportional to respective swings of the first and second oscillation signals and a reference voltage is reduced.
