Abstract

PURPOSE:To obtain an output at a high speed by detecting input signals with high sensitivity, by automatically driving a control circuit according to the potential difference between input signals. CONSTITUTION:Nodes N4 and N5 are previously charged to high potentials and at a proper stage, clock phi2 is held at a high potential. In this state, FETs Q1, Q2 and Q3 are all on and the potential of node N2 is determined by the beta ratio among FETs Q1, Q2 and Q3. Next, when nodes N4 and N5 have a potential difference by the 1st and 2nd input signals S1 and S2, FETQ3 decreases in conductivity and the potentials of nodes N2 and N1 rise. When the potential difference between nodes N4 and N5 exceeds the sensitivity of a control circuit, the voltage of node N1 turns on FETQ8 to drive the control circuit, increasing the potential difference between nodes N4 and N5. Consequently, the conductivity of FETQ3 further decreases and through regenerative feedback, node N4 is held at a low potential to the end to turn off FETQ3, thereby holding node N2 (output terminal) at a high potential.
