Abstract
A multi-deck circuit arrangement including a first deck circuit having a negative supply terminal and a second deck having a positive supply terminal connected to the negative supply terminal. A single power supply provides a voltage across both the first and second decks. The total power consumption will be less than the prior art of having both deck circuits conventionally regulated. The supply rail connecting the second deck's positive supply terminal to the first deck's negative supply terminal may be regulated. In one embodiment, the rail voltage can be controlled to optimize deck circuit operation for speed and power and to avoid level shifters when interfacing to other circuits.

Circuitry comprising:
- a first circuit comprising a first positive supply terminal and a first negative supply terminal;
- a second circuit comprising a second voltage positive supply terminal and a second negative supply terminal, where the first negative supply terminal is electrically connected to the second positive supply terminal;
- a voltage source comprising a first terminal and a second terminal, the first terminal being connected electrically with the first positive supply terminal and the second terminal being connected electrically with the second negative supply terminal, the voltage source being configured to provide a voltage across the first terminal and the second terminal;
- and
- dump circuitry including a true random number generator, the dump circuitry configured to regulate a voltage across one or more of the first circuit and the second circuit.
Circuitry comprising:
- a first circuit comprising a first positive supply terminal and a first negative supply terminal, the first circuit being configured to operate using a first voltage;
- a second circuit comprising a second positive supply terminal and a second negative supply terminal, where the first negative supply terminal is connected to the second positive supply terminal and the second circuit is configured to operate using a second voltage;
- a voltage regulator configured to regulate the first voltage and the second voltage by balancing current between the first circuit and second circuit;
- a voltage source comprising a first terminal and a second terminal, the first terminal being connected electrically with the first positive supply terminal and the second terminal being connected electrically with the second negative supply terminal, the voltage source being configured to provide a voltage across the first terminal and the second terminal;
