Operational Transconductance Amplifier OTA Compensator Design

Have you noticed that sometimes the compensator components on the output of the op-amp are tied to ground?
In this video Dr Ali Shirsavar from Biricha Digital explains an "Operational Transconductance Amplifier" or OTA works and how we design stable power supply compensators with OTAs

Finally decided learning this. I'm the spoilt kit used to throwing 1USD STM32 mcu with 5msps internal ADC and 80M clock at everything.

Thank you very much for the explanaiton Dr.Ali, there's not much information about OTA in youtube.

[@basaltnow]

perfect, now I am able to also use OTA which I obmitted in the past.

[@thusitha320]

I wish he told us WHY use a transconductance amplifier, instead of a normal voltage amplifier, if the whole thing is outwardly exactly the same

[@whatever3041]

He probably doesn't know that himself! Because I agree with you, that should have been the starting point of his lecture.

[@yaghiyahbrenner8902]

Thank you so much for this video, it was really well done.

Indeed OTA are alien to most textbooks. Question, can a general purpose OpAmp work as an OTA, or we need to purchase the right IC? Thx.

[@fursino]

Are PWM controllers embedding OTA? Will it be possible to have the designation of some of the IC that will have OTA? Thanks.

great trans-conductance info, could you please add the Vishay IL300 opto-isolator to the circuit for a 1:1 ratio 10vin/10vout and explain how it works to supplement the Vishay literature? thanks.
