Using OTA as an Integrator for Dual Slope ADC: Advice & Links

Thread starter salil87
Start date Sep 2, 2013

AI Thread Summary

Using an Operational Transconductance Amplifier (OTA) as an integrator in a dual slope ADC involves charging a capacitor with the signal output current and discharging it with a reference current. The placement of the capacitor is the primary distinction when integrating an OTA compared to traditional methods. For further understanding, reviewing the dual slope A/D article on Wikipedia is recommended. Clarification on specific aspects of the integration process may be needed for more detailed guidance. Overall, utilizing an OTA can enhance the performance of dual slope ADC designs.

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.

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
