TWO-MODULUS PRESCALER CIRCUIT |
摘要 |
<p>In the dual modulus prescaler circuit, an output terminal of the first multi-input logic gate circuit is connected to a data input terminal of a first D flip-flop circuit; output terminals of the first to (n-2)thD flip-flop circuits are, respectively, connected to data input terminals of the second to (n-1)th D flip-flop circuits; output terminals of the (n-1)th and nth D flip-flop circuits are connected to input terminals of the first multi-input logic gate circuit; the second multi-input logic gate circuit is connected to the output terminal of the (n-1)th D flip-flop circuit and receives a switching signal; and an output terminal of the second multi-input logic gate circuit is connected to a data input terminal of the nth D flip-flop circuit. Moreover, all the aforementioned connections are connections using differential signals. <IMAGE></p> |
