Abstract
An inverter includes an input inverter having a high-resistance load and a first transistor and an output buffer including second and third transistors coupled in series. A power supply voltage is provided to satisfy an inequality VDD>VDD+Vth where VDDis the power supply voltage of the input inverter, VDDis the power supply voltage of the output buffer, and Vth is the threshold voltage of the transistors. Use of the high-resistance load allows an output waveform to rise and fall quickly, as well as reduces current consumption.
