Abstract：

This　article　introduces　a　high-precision　and　low　temperature　coefficient(TC)　bandgap　reference　(BGR)　with　a　1.2　V　output　voltage　after　a　novel　digital　trimming.　A　multi-section　curvature　compensation　circuit　alleviates　the　variation　caused　by　the　temperature　dependence　of　the　base　emitter　nonlinear　voltage　of　bipolar　transistors.　The　novel　digital　trimming　technology　is　utilized　to　reduce　the　TC　and　improve　the　output　voltage　precision(VP)　of　the　proposed　the　BGR.　Designed　and　simulated　in　a　65　nm　CMOS　process　with　an　active　area　of　0.037　mm2.　Simulation　results　of　the　proposed　the　BGR　demonstrates　that　its　output　voltage　is　1.2　V,　the　best　TC　is　0.959　ppm/°C　over　a　−40　°C　to　125　°C　temperature　range　and　the　power　consumption　of　138　μW　under　3.3　V　supply　voltage　at　room　temperature　with　trimming.　In　the　supply　voltage　range　of　1.8–3.4　V,　the　line　regulation　(LR)　is　0.25%/V.　©　2023　Elsevier　Ltd
