Circuit for temperature stable bias and reference voltage source has n-MOS and p-MOS arranged in pairs to form two opposed current mirrors, further p-MOS transistor in one current path

摘要

The circuit has two n-MOS transistors (M1,M2) with two p-MOS transistors (M3,M4) and two further n-MOS transistors (M6,M7) in pairs to form two opposed current mirrors and a further p-MOS transistor (M5) is connected in one current path. A working point is set so that the transistors operate in the threshold and saturation regions of their current-voltage characteristic and the further transistor operates in the threshold and linear regions.
