    OTA is a component, integrator is circuit. What are your requirements for the integrator? What time constant?

    Well i need to use the integrator in a Dual slope ADC which integrates the sampled input. But since the input will be a large signal won't the gm vary at different input levels? Since I am a rookie I am a bit confused.
    Thanks
