Filed: 1993-12-21
Abstract: PURPOSE:To reduce the deterioration of gate speed along with the making of a low power supply voltage by supplying a second power supply with voltage higher than that of a first power supply to the source potential of a first P-type field effect transistor group. CONSTITUTION:The source potential of a P-MOS 122 which charges the base of a bipolar transistor(TR) 121 to the power supply voltage Vcc on the collector side of the TR 121 and the power supply voltage Vcc on the source side of a P-MOS 151 for pull-up support is set at Vcc+, and the source potential Vcc+ is set so that relation Vcc+>Vcc can be satisfied. By employing such constitution, since the MOS 122 is turned on and an N-MOS 124 is turned off when an input signal VIN at an input node N1 is set in an L level, the base of the TR 121 can be charged to Vcc+, and the TR 121 is turned on. In this way, output Vout of H level can be obtained. When the input signal VIN goes to the H level, the TR 121 is turned off and the MOS 122 is turned on, then, VOUT of L level can be obtained.
