Good OP structure
Dear All :
No I work in Delta-Sigma DAC design , I need a good opamp (single-end ) for
the low pass filter design, I read some paper , It need High DC gain about 90dB ,
Unit-Gain Bw is large 75MHz, The Noise is about 2~3 uVrms (20~20KHz). Does anyone work in this filed, And good OP Structure can share it , Thanks
