Chopper Amplifiers Demystified Kofi A. A. Makinwa

[@user-ii1ds3fy8z]

This is the best and easy-to-understand explanation I found for the chopper amplifiers on the internet. Thank you very much for this amazing presentation.

[@fmartinpirchio]

when you really know the matter, the explantion is simple and easy to follow. Dr Makinwa video is great for saving a lot time

[@vizier_of_the_dead]

I really loved the way Dr. Makinwa presented the topic. It was very simple and to the point. Never thought my search for the answers would be so quickly solved by his lecture. Please give Dr. Makinwa my regards.

this is a very simple yet very insightfull explanation , thank you.
so you basically up-convert the input signal to a chopping (carrier) frequency but not the offset, then buy de-modulating the output and filtering you get rid of the offset ... amazing

Very helpful to exemplify and understand the properties of chopper.

Thank you Dr. Makinwa for this very clear and concise explanation.

Thanks, best presentation of chopper technique out there!

[@qing9456]

Thank you for explaining this concept in such a simple yet clear way.

fantastic quick lecture

Thanks!

Thanks！

[@sundarchannel]

Thank you.

[@creativeworldwithhibbafarm1210]

some papers quote Zin = 1/(2*fchop*Cin). Here Zin = 1/(4*fchop*Cin). How this number 2 or 4 comes into equation and why they are different? Thanks

[@monglebest]

At 12:19, why current mode output choppers have wide BW? and hence high Aeff? current mode mean low input impedance so it's high BW?

[@manikanthsativada2678]

how do we reduce the output riplle from lpf using chopping frequency?

[@manikanthsativada4553]

Can anyone provide the math involved in chopper amplifier

[@007viviadam]

Can anyone explain the math behind the demodulation process. How can the same clock again bring back the spectrum to original signal ?

[@Intuizon]

Its like a mixer

[@manikanthsativada4553]

Please help with some paper referal or video or whatever way possible.
