An interesting analog calibration technique was reported by Moon et al. [33].
The technique uses a thermometer-coded SC DAC similar to that in Figure 5.3(a) as
the demonstration platform. The basic idea is to adaptively calibrate the charge
delivered via each input branch by using a variable reference voltage for each branch
(similar to the current copying and the reference refreshing techniques reported in
[18] and [25], respectively), until all branch charges accord with a single reference
charge value, which is rectifi ed by an accurate capacitor (i.e., the nominal C). In
