基准电压电路和电子器件
摘要：
提供一种基准电压电路，其中减小了用于基准电压电路的电压的差异，使得相应的输出电压的差异变小。耗尽型MOS晶体管(3，6)分别串行连接两个ED型基准电压电路中的耗尽型MOS晶体管(1，4)的漏极。串行连接的耗尽型MOS晶体管(3，6)中的一个晶体管的栅极连接另一个MOS晶体管的源极，所述另一个MOS晶体管的栅极连接所述一个MOS晶体管的源极。这样，用于相应的ED型基准电压电路的电压的差异被减小，使得相应的输出电压的差异变小。
摘要（英）：

A reference voltage circuit is provided in which a difference of voltages applied to reference voltage circuits is reduced so that a difference of respective output voltages is made small. Depletion type MOS transistors (3, 6) are respectively connected in series with the drains of depletion type MOS transistors (1, 4) in two ED type reference voltage circuits. The gate of one of the series-connected depletion type MOS transistors (3, 6) is connected with the source of the other MOS transistor and the gate of the other MOS transistor is connected with the source of the one MOS transistor. Thus, a difference of voltages applied to the respective ED type reference voltage circuits is reduced so that a difference of respective output voltages is made small.
