Yes. I meant that the bandwidth should stay unaffected as long as slewrate 
limit is not exceeded. Obviously when maximum slewrate is exceeded, the 
"bandwidth" (not really meaningful as the circuit will distort like hell) 
will be reduced.

How does one do this without requiring matched transistor pairs or similar 
components? I suppose OTA would be one way (Iabc is the maximum current).
