Abstract
A buffer has an amplifier that receives an external signal, a reference voltage, and outputs an amplified signal. The amplified signal is responsive to the difference between the external signal and the reference voltage. An inverter receives the amplified signal and generates an inverted signal. A voltage supply circuit is configured to provide an adjusted power supply voltage to the inverter responsive to the reference voltage. A ground voltage supply circuit is configured to provide an adjusted ground voltage to the inverter responsive to the reference voltage.
