Abstract

PURPOSE:To make is possible to obtain a reference voltage source which guarantees its accuracy sufficiently, by constituting a circuit of 5 MOSFET's consistihg of P channels and N channels, and 2 resitances, and controlling the threshold voltage of each FET. CONSTITUTION:The gate of MOSFET1 and the gate and drain of MOSFET2 are connected in common, and also the gate and drain of MOSFET4 are connected to the gates of MOSFETs 5, 6. And, FET4, 1 and the resistance 3, and MOSFETs 5, 2, and MOSFET6 and the resistance 7 constitute the series circuits between the positive electric power source +VDD and the ground, respectively, and the terminal 9 is used as an output point of the reference voltage V0. In this circuit, FETs 1, 2 and FETs 4-6 are constituted of N channels and P channels, respecrively, the threshold voltage of FET2 is made larger than that of FET1, and the threshold voltage of FETs 4-6 is made equal to that of FET 1. The difference of said threshold voltage is decided by the ion charge quantity Qi, the charge quantity can be controlled with good accuracy, therefore the reference voltage with high accuracy can be obtained.
