Abstract
PURPOSE: To continually keep the potential of input signals for conducting a MOS.FET constant, by forming a bias circuit so that bias value change in the same manner as the variation of threshold voltage.
CONSTITUTION: The potential of a joint 19 is brought to potential near threshold voltage from the I-V characteristics of a MOS.FET 17, which short-circuits a gate and a drain, and a load curve of a resistance 18. The potential is divided by means of resistances 15 and 16. A gate of a MOS.FET 12 has voltage lower than threshold voltage, and is biased to adequate value near approximate threshold voltage. When threshold voltage changes from fixed value, the potential of the joint 19 also alters in response to the change of the threshold voltage. Thus, the potential of input signals for conducting the MOS.FET 12 does not depend upon the dispersion of threshold voltage.
