Amplifier circuit for CMOS operational amplifier |
摘要 |
An output circuit 1 has a p-type MOS transistor Q1 connected between a power-voltage node and an output node, and an n-type MOS transistor Q2 connected between a ground-voltage node and the output node. A voltage-current conversion circuit 2 outputs a voltage according to the voltage difference between an input signal and the comparison voltage. According to the output from the voltage-current conversion circuit 2, a signal conversion circuit 3 controls the voltage of the gate electrode of the MOS transistor Q1 with a reference of a second specified voltage, and controls the voltage of the gate electrode of the n-type MOS transistor Q2 with a reference of a first specified voltage.
