Abstract
A level shift circuit comprises an inverter connected to a first voltage supply source and supplied with an input pulse. A condenser and a directional switching element are connected in series between the output point of the inverter and one potential point of the first voltage supply source. The input of a first MOS-FET is connected to the output of the inverter while the input of a second MOS-FET is connected to a connection point between the condenser and the directional switching element. The source of the first MOS-FET is connected to a common terminal of first and second voltage supply sources while the source of the second MOS-FET is connected to the other terminal of the second voltage supply source. An output voltage is generated between a common connecting point of the drains of the first and second MOS-FETs and one potential point of the second voltage supply source.
