Question
If we put the OFDS line to disable offset correction loop (a switch on Figure
46 is off) is a voltage on capacitor Cofs proportional to the output baseband
DC offset or is this voltage reset?
Answer
The voltage on the cap will slowly degrade to an off state. It should be close
to ground. There may be some small residual voltage where the FETs are off and
don’t degrade the voltage anymore. I’m guessing it should be 0.5V or less.
