Abstract: |
The invention relates to a low voltage and can provide the linearity and input scope transconductance amplifier, its characteristic is that introduced a new local feedback structure in the traditional source level weaken structure. The feedback structure made two low resistivities anti- pitch points in the source level damping resistance two terminal, the low resistivity anti-pitch point reduced the traditional source level weaken structure distortion. The structure overcame the traditional transconductance amplifier defect of litter input scope under the low voltage, the linear inferior and so on, simultaneously the electric circuit most voltage drop on the key way is smaller than the traditional structure circuit, thus brought out the working potential under the low voltage. The circuit characteristic is that suitable for the low voltage work, the high linearity and the big input scope, the structure completely conforms to the present integrated circuit research and development direction. |
