    摘要： Controlling the supply voltage with high precision irrespective of variations in threshold. A bypass transistor is connected between power supply terminals and provides a bypass path of an excessive current flowing when the supply voltage increases. A resistor is connected between the source of the bypass transistor and the power supply terminal. A bypass control circuit applies a constant voltage to the source of the bypass transistor and also applies a threshold voltage of the bypass transistor between the power supply terminal on the source side and the gate of the bypass transistor.

    摘要： Disclosed is a rectifier circuit that realizes a low threshold voltage without using a process step to enable reduction in cost and in variation of devices. An NMOS transistor has a threshold voltage. In the transistor, a voltage to be rectified is inputted to a second node, and a rectified voltage is outputted to a first node. A threshold voltage generator is connected to a gate of the transistor and the first node. The generator generates a voltage and outputs it to the gate of the transistor. The voltage is a voltage which is elevated by the threshold voltage with respect to a voltage of the first node and is decreased by a microvoltage sufficiently small with respect to the threshold voltage. Thus, when the voltage of the second node is decreased by the microvoltage or more with respect to that of the first node, the transistor is turned on.
