Embodiment approach
[0024] refer to figure 1 As shown, an implementation manner of the operational amplifier circuit of the present invention includes:
[0025] The input structure, which takes the signal and transmits the signal to the output structure;
[0026] The output structure amplifies the signal transmitted by the input structure;
[0027] Feedback network, which extracts the signal amplified by the output structure and feeds it back to the input structure;
[0028] The bias network simultaneously powers the input structure, the output structure, and the feedback network.
[0029] In the operational amplifier circuit of the above embodiment, the output signal of the output structure, that is, the output signal of the entire operational amplifier is monitored through the feedback network.
[0030] In the operational amplifier circuit, a low-voltage high-gain operational amplifier is used to clamp the potential of the input terminal, and ensure that the input voltage value of the input ...
