Low noise selective differential amplifier
The amplifier has a pair of transistors (20, 22) including sources connected to a current source and gates connected to a set of differential voltage sources (26, 28). A transconductance circuit (12) with input nodes (120, 130) is connected to a set of load circuits (14) via a cascode circuit (16)....

| Zusammenfassung: | The amplifier has a pair of transistors (20, 22) including sources connected to a current source and gates connected to a set of differential voltage sources (26, 28). A transconductance circuit (12) with input nodes (120, 130) is connected to a set of load circuits (14) via a cascode circuit (16). A prefilter circuit (18) is connected between the input nodes and differential voltage sources. A set of coupling circuits e.g. capacitive circuit, is disposed between a gate of respective transistor and a source of respective transistor. |
