Abstract: |
This invention relates to a low voltage negative feed back transconductance amplifier characterizing that it combines the advantages of current negative feedback, overturn voltage follower and source attenuation to overcome the shortcomings of small input amplitude, poor linearity not suitable for low voltage, this invented current negative feedback module increases the input amplitude of the transconductance amplifier, the low resistance node of the overturn voltage follower module combined with the source attenuation structure reduces distortion brought with the traditional source attenuation, and the introduction of the low resistance node brings free design to circuit. |
