Abstract
A differential amplifier compares a potential difference between a first input (A.sub.in) and a second input (V.sub.r) and provides complementary output signals (A, A). The differential amplifier comprises a flip-flop (20) having nodes (N1, N2) and nodes (N3, N4) and a fixing means composed of N-channel FETs (33, 34) having drains connected to the nodes (N3, N4) of the flip-flop circuit (20) and sources connected to a second potential (V.sub.SS) and inverters (31, 32) having inputs to which output signals (A, A) are applied and outputs connected to gates of the N-channel FETs (33, 34). The fixing means detects a potential drop of the output signals (A, A) and fixing the nodes (N3, N4) connected to the nodes (N1, N2) to the second potential (V.sub.SS).
