I have been looking at different references about the Chopper Amplifier and all of them mention that the Duty Cycle MUST be 50%.
( see page 27 of www.ewh.ieee.org/tc/sensors/Tutorials/makinwa.pdf)
As far as I can see, as long as the modulator and demodulator both use the same chopping signal, the duty cycle is not important.
My questions:
What will be the influence of changing the duty cycle?
How will this affect the residual offset noise?
Any links or references are very much appreciated.
Thanks!!
