Reference voltage generation circuit for e.g. analog to digital converter, has current sources respectively connecting gate and drain of corresponding P-channel metal oxide semiconductor transistor to voltage application terminal and ground

摘要

The circuit has a current source (31) that connects a gate of a P-channel metal oxide semiconductor (MOS) transistor (MP0) to a voltage application terminal (2). A current source (22) connects a drain of a P-channel MOS transistor (MP1) to the ground (3). The transistor (MP0) connects the source of the transistor (MP1) to the terminal and has its gate connected to drain of the transistor (MP1) by an N-channel MOS transistor (MN0).
