Title: Clock receiver circuit
Inventor: MATSUI YOSHINORI
IPC: H03K19/0175
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To shorten the time from the input of a clock signal to the generation of an internal clock signal and to shorten access time by transiting the level of an output level before the input level of the clock signal is varied with a signal generated by delaying the output signal. SOLUTION: With the signal 104 generated by delaying the output 115 of a buffer circuit 114, the level of an output node 103 of a differential input receiver circuit is transited before the system clock signal CLK varies in input level. Consequently, the threshold value of a following buffer circuit 114 can be cut speedily in response to the variation in the input level of the clock signal CLK. Therefore, a current path of an output node 103 is formed before the inputted clock signal varies. Thus, the time up to the generation of the internal clock signal ICLK is shortened and access can be made fast.
