Abstract

PURPOSE:To enhance the temperature characteristics for the circuit which obtains the complementary output via the active load amplifier, by varying the threshold level signal in agreement with the DC level fluctuation caused by the temperature change of the output signal from the amplifier circit. CONSTITUTION:Active load amplifier 4 containing active load amplifying step 12 is provided at the collector side of differential transistor circuit 9 to which the input signal is applied. And then reference circuit 6 is added to deliver the threshold level signal which is in agreement with the fixed central level of the output signal supplied from amplifier circuit 4. Circuit 6 consists of the voltage drop circuit in which diode-connected transistors Tr22-24 and resistance R25 are put in series, and the threshold level signal is varied in agreement with the fluctuation of the DC level against the temperature change of the output signal from circuit 4. Thus, the temperature change of the output signal from circuit 4. Thus, the temperature characteristics can be enhanced for the comparator circuit.
