Operational amplifier and digital signal transfer circuit |
摘要 |
An operational amplifier and a digital signal transfer circuit in which an output voltage does not decrease instantly even if an abrupt change of input signal due to noise causes a high-to-low transition to be superposed on an input signal. The operational amplifier includes a differential pair of transistors with a first transistor having a collector that is grounded and a second transistor having an emitter connected to the emitter of the first transistor; a current mirror circuit with a third transistor having a collector connected to an output node of the differential pair of transistors and a fourth transistor having a base connected to a base of the third transistor; a fifth transistor having a collector connected to an output terminal and a base connected to an output node of the current mirror circuit; and a capacitive element connected between the output node of the current mirror circuit and the output terminal.
