Output characteristics of CMOS chips are controlled by providing a known and stable current to a representative transistor (58) of known relative size in the CMOS chip, and arranging the output CMOS driving transistors (T3) of the chip, which are of known size relative to the representative transistor, in current mirror relationship with the representative transistor (58). The representative transistor (58) is a diode-connected transistor with a saturation current which is generated by a current source (59b) and which is also provided to drive the output transistors (T3) when it is on.
