I want to design a cyclic ADC and at this time I want to implement and design an Opamp for this purpose. my ADC features are: Fs:20 MS/s Number of bit:12 could you tell me what the parameters are for Opamp ? I design an Opamp with these parameters but it doesn't work in my ADC. Gain=60 db phase margin=60' bandwidth=850 MHz what is the best structure for Opamp in this kind of ADC. Please help me. I need your help. best wishes A.Jafari
