Abstract
Various methods and devices that involve electronic circuits are disclosed. A disclosed method includes buffering an input signal using a first buffer. The first buffer is powered by a supply voltage and a reference voltage. The method also includes buffering the input signal using a second buffer. The second buffer is powered by the reference voltage and a ground voltage. The method also includes level shifting a first buffer output signal of the first buffer to a voltage range using a first level shifter, and level shifting a second buffer output signal of the second buffer to the voltage range using a second level shifter. The voltage range is larger than a delta between the supply voltage and the reference voltage. The reference voltage is greater than one quarter of the supply voltage and less than three quarters of the supply voltage.
