SYNCHRONIZING TYPE MODULO N COUNTER USING D FLIP-FLOP

摘要

PURPOSE: A synchronizing typed modulo N counter circuit is provided to have the whole simple hardware constitution, and to reduce the constitution size of the hardware, and to reduce the power consumption. CONSTITUTION: The synchronizing typed modulo N counter comprises: a device(10) to output by counting up an input signal; at least two D flip-flops(20,30) to output the signal inputted from the count-up device. The output of the D flip-flops is the feedback by the count-up device. The count-up device counts to 0 when the signal inputted form the D flip-flops is a binary number(N-1). The whole hardware constitution is made simple by organizing the D flip-flop for a JK flip flop on the synchronizing typed modulo N counter circuit.
