Abstract
Plurality of current mirror circuits CMto CMat which the same amount of current Iflows in the circuits. Transistors Qa/Qbare ON state when it is in the steady state. Transistors Qa/Qbturn ON and transistors Qb/Qaturn OFF when a voltage generation circuitapplies a voltage more than predetermined value Vto node N. Therefore node Nbecomes fixed voltage V. On the other hand, voltage generation circuitapplies a voltage less than predetermined value Vto node N, transistors Qb/Qaturn ON, and transistors Qa/Qbturn OFF. Accordingly, the node Nbecomes fixed voltage V
