OTA question

[Haible_Juergen#Tel2743]

Hi!

I got a question about OTA configurations.
Using a CA3080 plus a buffer opamp, there are
basically two possibillities to build VCA's or
VC-integrators:
(1) the OTA feeding a resistor/capacitor to gnd,
      plus an opamp as unity gain buffer
(2) the ota feeding an inverter/inverting integrator
      built of an opamp and a resistor/capacitor in it's
      feedback loop.

I wonder which approach is the "better" one.
As we can use both inputs of the OTA, signal inversion
should not be a point.
As far as I can guess, (2) would be easier for the OTA's
output stages (constant Vce), but there might be advantages
of (1) as well. Any ideas? Any pointer to good literature
about this ?

Thanks,

JH.
