  • Voltage level shift circuit and semiconductor device
    Patent number: 8436655
    Abstract: A voltage level shift circuit in which a difference in response characteristic depending on the signal level of an input signal is suppressed. The voltage level shift circuit generates an output signal VOUT having a voltage amplitude different from that of the input signal. An inverter INV2 generates a voltage V1 in the range of VSS to VDDI according to the input signal. An inverter INV3 generates a voltage V2 in the range of VSS to VPERI according to the input signal. An inverter INV4 generates the output signal VOUT according to V1 and V2.
