when the input negative power in the positive and negative power supply circuit is turned off before the input connection power, due to the characteristics of the FET, than the positive output voltage of the off-off of the negative output power providing positive and negative power supply circui...
The first voltage distribution unit 24 receives input voltage shifting between a ground voltage and a positive voltage, and converts the input voltage to a first distribution voltage shifting, between a positive voltage and a first negative voltage. The first drive unit 26 converts the first ...
PURPOSE:To obtain a positive/negative output generating circuit suitable for generating an output current having bidirectionality by being equipped with a current mirror composed of two three-terminal elements and a switching element provided between a terminal connected mutually to the current mirror and...
aA circuit for a voltage-to current converter having low noise and low transconductance comprising: a positive and a negative input voltage; circuitry to shift input voltages higher to enable an input stage of a differential operational transconductance amplifier to operate in saturation mode for MOS...
A negative-voltage circuit for realizing a flash memory is installed independently and is applied selectively to word lines in response to signals sent from row decoders. Row decoders for specifying word lines need not be installed in the negative voltage circuit. The negative circuit can therefore...
