Abstract
An amplifying circuit includes a differential amplifier having a positive input end, a negative input end, a positive output end, and a negative output end; a first input impedance coupled between the negative input end and a first input signal; a second input impedance coupled between the positive input end and the first input signal; a third input impedance coupled between the negative input end and a second input signal; a fourth input impedance coupled between the positive input end and the second input signal; a first output impedance coupled between the negative input end and the positive output end; a second output impedance coupled between the negative input end and the negative output end; a third output impedance coupled between the positive input end and the positive output end; and a fourth output impedance coupled between the positive input end and the negative output end.
