Level-shift compensation in m.o.s. bucket-brigade circuits operated in an analogue mode
As a result of net loss (or gain) of charge to the substrate, the signal component at the output of a bucket-brigade circuit is subject to a direct-voltage shift which reduces the dynamic range of the device. Compensation for such level-shifting (of either polarity) can be provided by means of single additional m.o.s. devices placed at suitable intervals along the delay line.
