Abstract
Various embodiments include apparatus, systems, and methods having a reference node to receive a reference voltage, a first node to provide a signal, and a circuit. Such a circuit may include a second node to receive different voltages greater than the reference voltage and to cause the signal at the first node to switch between a first voltage greater than the reference voltage and a second voltage greater than the reference voltage. Other embodiments including additional apparatus, systems, and methods are described.

- a first node to provide a signal;
- and
- a circuit including a second node to receive different voltages greater than the reference voltage and to cause the signal at the first node to switch between a first voltage greater than the reference voltage and a second voltage greater than the reference voltage.
An apparatus to switch signals, the apparatus comprising:
- a first supply node to receive a first voltage greater than zero;
- a second supply node to receive a second voltage greater than zero;
- a first node;
- a second node;
- and
- a circuit to operatively couple the first node to the first supply node during a first time interval and to operatively couple the first node to the second supply node during a second time interval, and the circuit to hold the second node at a voltage less than the first voltage during the first time interval and to operatively couple the second node to the first supply node during the second time interval.
An electronic system comprising:
