My textbook just claims that this is good without any detail analysis and references. Don't know how to analyze it, can anyone explain how it works or give some reference about it? thx Last edited: Mar 8, 2018

Figure 3-9: This circuit ... achieves zero TC by summing a positive TC current from a bandgap cell with a negative TC current. Click to expand... See Burr-Brown (now TI) Application Bulletin SBOA046, p.2, FIGURE 3: REF200 Current Source uses a similar architecture.
