Patent JP-H0215710-A (JP)
Title: Metastable detection circuit
Inventor: TAKENO MINORU
IPC: H03K3/02
Filed: 1988-07-04
Abstract: PURPOSE:To detect the metastable state of a signal to be tested by deciding outputting states of the multi-input gate circuit of a CMOS NAND gate element and the multi-input gate circuit of a CMOS OR gate element from outputs of the both gate circuits. CONSTITUTION:At a NOR 21, potential of logic '0' is previously inputted to #2-#m of the input terminal 23 except #1 after adjusting the value (m). At a NAND 22, potential of logic '1' is previously inputted to #2-#n of the input terminal 24 except #1 after adjusting the value (n). When the potential of the output OUT of an FF1 gets into the range between the lower and higher thresholds, the output OUT is fetched to each FF 4 and 5 by means of a clock CLK #2 which rises at the timing t3 lagging in phase from the rising timing of a clock t1 by prescribed time DELTAt. Therefore, the output of an EOR 6 rises from logic '0' to logic '1' after the timing t3 and the metastable state of the output OUT of the FF 1 can be detected.
