Abstract

PURPOSE:To obtain a high speed, high sensitive and highly stabilized sensing circuit, by providing an MOS transistor receiving an output to a gate, between a common connecting point of a source and a power supply. CONSTITUTION:Assuming that a signal Y is at H level, a sensing amplifier is operative and an in-phase component Vc of inputs DB and DB' is fluctuated and the DB and DB' are both increased. First, a transistor (TR)QA4 turns on, QA1 and QA2 are also driven to be on-state and outputs SD and SD' both drop. On the other hand, when the inputs DB and DB' drop, the TRs QA1 and QA2 are driven to off-state, and a common source potential Vs drops. That is, this circuit is operated suppressively against the in-phase change of inputs to rise or drop the common source voltage Vs being a reference point to the input signals DB and DB' together with the said input signal.
