Title:
VARIABLE FREQUENCY DIVIDER CIRCUIT
Document Type and Number:
Japanese Patent JP2002217710
Kind Code:
A
Abstract:
To provide an F/F+1 prescaler that is stably in operation by a low consumed current at a low power supply voltage.
The size of MOS transistors(TRs) (50, 51) for frequency division ratio switching is selected greater than that of other differential stage MOS TRs (28-31) and differential signals (FBB, ZFBB, FBA, ZFAB) are delivered to a latch circuit at a 1st stage as feedback signals.
