Abstract :
This paper explains the choice made for a full differential operational amplifier. This op amp has been designed for the first stage of a pipelined A/D Converter (ADC). This means that it has the highest specification of every op amp of all stages, as it concerns the LSB of the ADC. It shows also the solution founded to reach high gain and short settling time, without degrading too much the output swing.
First the operational amplifier specification are explained; the different structures tested are then presented and the motivation of the final topology choice are shown. It presents then the op amp schematic implementation, the simulation results and the layout with the 0.35um CMOS-AMS design kit. |
