Voltage Level Shifting

An electronic device, comprising:

• a pair of current mirroring transistors coupled to one another, the current mirroring transistors including a first mirroring transistor and a second mirroring transistor and configured to mirror a drive current passing the first mirroring transistor to the second mirroring transistor;
• a pair of differential input transistors coupled to the pair of current mirroring transistors, the input transistors including a first input transistor and a second input transistor and configured to receive at least a first input signal;
• a first swing-clamped transistor coupled between the second mirroring transistor and the second input transistor, wherein a gate and a drain of the first swing-clamped transistor are coupled to each other;
• a switching transistor coupled between the first mirroring transistor and the first input transistor, wherein a gate of the first swing-clamped transistor is coupled to the gate of the switching transistor;
• and
• a first output stage coupled to the first swing-clamped transistor and configured to generate a first output signal.

A method for converting voltage, comprising:
