SUMMARY

The discussion focuses on utilizing an Operational Transconductance Amplifier (OTA) as an integrator in a Dual Slope Analog-to-Digital Converter (ADC) setup. Key insights include charging a capacitor with the signal output current and discharging it with a reference current. The placement of the capacitor is highlighted as a critical factor when integrating an OTA into this configuration. For further understanding, the dual slope ADC article on Wikipedia is recommended as a foundational resource.

Hi
I just want to get some idea how to use an OTA as an integrator (for dual slope ADC). Can some one help me out or give me some links?
Thanks

You charge a capacitor with the signal output current, and then discharge it with the reference. Not really sure what you are asking. Read the dual slope A/D article at wikipedia. I think the only difference with an OTA is where you put the capacitor.
