摘要： An IIL reset circuit includes an IIL inverter having input and output terminals, and a capacitor connected to the IIL inverter through the input terminal. When the IIL inverter is supplied with a constant current, it charges the capacitor through the input terminal, and outputs a reset pulse through the output terminal. The reset pulse has a pulse width that is determined based on both a current supplied to the capacitor, and on a capacitance of the capacitor.

摘要： In a negative voltage output charge pump circuit, first a capacitor C1 is charged with a positive voltage Vin relative to a reference voltage, and then the high-potential terminal A of the capacitor C1 is made to conduct to the reference voltage and simultaneously the low-potential terminal B of the capacitor C1 is made to conduct to an output terminal OUT so that the voltage with which the capacitor C1 is charged is output as a negative voltage −Vin. Here, at least one of the switching device DP1 that is kept on while the capacitor C1 is being charged so as to apply the reference voltage to the point B and the switching device DP2 that is kept on while the negative voltage is being output so as to make the point B conduct to the output terminal OUT is a depletion-type transistor. This configuration makes it possible to realize a negative voltage output charge pump circuit that is free from malfunctioning caused by a parasitic device, that operates with low loss, and that can be produced at low costs.
