A level shift circuit comprising two terminals which are different in potential level, at least two capacitors each incorporating a ferroelectric material and connected to each other in series between the two terminals, and output terminals each provided on one side of each of the capacitors, whereby the output terminals are capable of outputting respective signals which are different in direct-current voltage level.
A level shift circuit comprising at least two capacitors each incorporating a ferroelectric material and connected to a source of a field effect transistor in series wherein drain is connected to a power supply terminal, output terminals each provided on one side of each of the capacitors, whereby the output terminals are capable of outputting respective signals which are different in direct-current voltage level.
A level shift circuit comprising at least two capacitors each incorporating a ferroelectric material and connected to each other in series, and a field effect transistor with a source connected to one of said at least two capacitors, and a gate of said FET connected to an output terminal of a differential logic circuit which varies a current value depending on whether an input voltage is higher or lower than a reference voltage, wherein output signals at said at least two capacitors are different in direct-current voltage level.
