Title:
FREQUENCY DIVIDER CIRCUIT
Document Type and Number:
Japanese Patent JP3703347
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a frequency divider circuit from which a frequency division ratio of 2 over odd numbers with a simple circuit configuration.
SOLUTION: The frequency divider circuit comprises a flip-flop multi-stage circuit G consisting of n-sets of flip-flop circuits, two OR circuits A2, E2, two AND circuits B2, C2, and an inverter circuit N2. Then an input signal IN is frequency-divided into 2/(2n-1) and a frequency division output signal E2 is obtained.
